AFR Vs MTI heads
2- AFR with G5X3 put down about 470 (On a Vette LS6, not an LS1). But that was not stock AFR's (11.4 CR). Off the shelf AFR are 66cc chambers and require a spring upgrade. So prices will be close to $2500.00
The question was MTI 2E or 205 AFR
5.3 Stage 2E are $1795.00 (With Tit retainers and spring seats, 58cc, High lift springs, flow tested etc..) In brief the "Works". They will flow over 300 intake and 210 Exh. And best of all, they have been tested for a few years.
I worked out a H/C package for the price of a set of AFR's. (2E, cam, P-rods, gaskets, ARP bolts) Quality package from a renown quality service shop.
Predator-Z...
Your senseless negative commentary concerning the new AFR "LS" heads in a couple of previous threads had me a little upset, primarily because your comments had zero factual content to them. I really don't understand your negative agenda concerning our new product, but now you have crossed the line prompting me to respond based on this post which has completely INACCURATE information. Please take the time to find out the facts before posting your opinions and commentary.
#1 AFR has most certainly put down 470+ to the tire with a 224/228 cam. In fact, with a 90mm TB installed just this Sunday, we rocked the dyno at LAPD to the tune of 476 HP/ 431 Ft/lbs....with the street friendly 224 cam still in the motor. Thanks for giving me an excuse to share that...
#2 All of the chassis numbers I have been referring to with our 224/228 package are in fact being developed with a bone stock 2000' LS1 shortblock that has 45 K on the clock....not a "fresh" Z06 block which would indeed make a little more power due to less windage losses and perhaps better ring seal.
#3 The compression ratio of the 224 engine in question is 11 to 1....not 11.4 to 1. Your getting confused with Lou's results on a different car he just tested which put down 484 HP with his GX3 cam and a modified Z06 intake.
#4 AFR heads are in fact 66 cc's out of the box, and we charge $100 to flatmill for less chamber volume and higher compression. Our standard springs are extremely high quality dual's that we conservatively rate to .600 lift. Most people won't need a spring upgrade but in the event that they do, it only costs $80.
I cant wait till some of the guys start receiving their new AFR's and start posting pics....when you guys see the quality of our completely new castings, as well as the quality of the CNC porting and machine work, you might just want to purchase three castings to have one to keep in the garage to show your buddies...
OK....I'm done

What poeple want (The other open eyed poeple) is a straight swap from stock LS1 motor to stock + AFR. No cams, no gimmics, no headers, nothing. 1 to 1 swap. regular heads VS AFR.
Then IMO we will see the whole truth and nothing but the truth. Just the way it is supposed to be. Do it on a 2001-2002 that way you can't blame the intake or the exhaust manifolds and guess what? Even the injectors will handle the max your heads can put on a STOCK LS1 engine.
And I quote from your own site:
1250" OD HYDRAULIC VALVE SPRING WITH DAMPNER, 130 LBS ON SEAT, 0.581 MAX. LIFT #8017 (UPGRADES AVAILABLE)Why be conservative? Just say the truth or do you think we wouldn't understand? What other facts are being kept from your consumer?
So Tony,

Unless you pay the $150 per month fee, your opinion means nothing...

You can research, debate, pose questions and generally get several perspectives and viewpoints on any given subject, so I thought I'd join in and throw my .02 in the ring
Bottom line? I feel that AFR makes a very good product as do we. And I'd advise any customer to weigh the information available to him and make the decision that he feels is right at the end of the day.
My job in representing MTI is the same as Tony's at AFR or any of the other sponsors of this board - provide a quality product at a competitive price, respond to customer's needs and requests in a timely fashion and try to do the right thing, day in and day out, the first time, every time.
Beyond that, hey it's your money! Spend it on what you like and what you want, but above all have fun doing it!
If I can answer any questions about any of MTI's products, please feel free to e-mail me directly davidc@motorsporttech.com
Best regards,

I made no reference to that.And excuse me but a "bone stock LS1" does not have a 224/228, 90MM TB, lsx intake, Headers etc....
Maybe I'm confused...but he said bone stock LS1 shortblock I have no doubt every one of them are professional when it comes to knowledge and product. After all, we ultimately care most about the quality and performance of the products we purchase. But we’d have a much more pleasant buying experience with a company that answers our emails, cares about our needs, and wants to help us reach our goals.
To me, good customer service is:
1. Responding in a timely fashion to inquiries. (A few days, not a few weeks, months or no response at all)
2. Listening to and understanding a customer’s wants and needs.
3. Recommending a quality product or products to help them achieve those wants and needs.
4. Providing that product with some sense of insurance (albeit a warranty or even word of mouth if there is a trusting relationship established) in case the product is defective or there was a mistake during installation (if install was included).
5. Providing all paperwork if applicable (dyno sheets, a/f ratio, compression ratio, head flow numbers, cam specs, parts used, labor involved, etc.)
6. Attention to detail.
7. The ability to admit an error or mistake.
8. Doing everything possible to correct an error or mistake.
9. Occasionally following up with the customer to make sure they are happy with the product and service they received. (Always a chance for repeat business you know?)
10. Competitive pricing.
I listed number 10 last because it should be the least important of all if a company is consistently able to provide the previous nine. I realize some customers are nearly impossible to please and can be very unrealistic but that should be determined during number 2. I wouldn’t want to sell a customer a set of heads who expects to go high 9’s on the stock bottom end. That should be a red flag because that’s obviously very unrealistic and I’d probably recommend they find someone with a better set of heads.
All I know is if I had the knowledge and resources that some of these people/companies have, that is the way I would strive to handle my customers. The smarts and craftsmanship are there; I’d just like to see some better customer service in this industry. I’m not saying it doesn’t exist, I’m just saying that I have yet to be impressed.
But now I’m looking for a good set of heads and a big cam to compliment the heads and my overall set up. So for these types of internal mods I just think there are other vendors that would be a better choice.

Man this is great info ThanX for the replys....

Well, in this world of "internet access" and "instant gratification" your response doesn't surprise me... It's just like the Corral and other such sites..
Though I will not try to explain the "other" shop's lack of response time but you need to understand that an "Email Request" is a minor priority for most businesses that have customers ready and waiting "in person" to spend their money. Some may have actually taken the time to stop by... Where would YOU spend your time?
If you were in this business, how would YOU address the hundreds of "Email requests" for information that net zero income? Would YOU just ignor the "paying" customer to answer that "request for info"??? Would YOU spend every moment of time on the internet doling out free information, ignoring the real customers? Did you get an empty paycheck at the end of the week?
Come on, you've got to understand the reality of the priority between a REQUEST versus a SALE...
Look, if the shop is busy, and takes a while to get to your request, that's a sign they are busy and FOR A GOOD REASON! Ever wonder why the best restaurants have a waiting line whereas the mediocre ones don't?
Maybe you need to refine your requests?? I get "Email Requests" for cam designs and "rough specs" all the time that I do not answer... All kinds of backdoor ways to try to pry the specs out of me like "how does this sound" or "what if this was done". All for naught because to play, you gotta pay. Like I said, YOU don't work for free... Do you?
Sorry but with this kind of logic, if OJ was on the internet looking for legal advice, he'd be looking at a needle now... For himself it's a good thing he didn't 'cuz he surely got his money's worth and he literally got away with murder!

If a shop is ALWAYS too busy that is a sign the company is ready for growth.
Hire more people, take in more customers and make more money. If a shop is ALWAYS too busy that is a sign the company is ready for growth.

Are you aware what its involved financially for hiring one person when it comes to a small buisness? I am not trying to get into a pissing contest, I am asking a legit question. me when I found out--->
