SB, the B1 is an old style cam! The reverse split cam (like the X1 cam) will give you more rwhp with no problem! I have seen cars get great gains from a reverse split cam. You should gain an easy 10 to 15 rwhp!

This is just what I have seen!

I have to say I have read a lot of blanket statements.. I can tell you that in my area we have all the vendors heads pretty much. Only one car is over 420rwhp and the heads are not owned by GTP.. The avg is 400rwhp.. Period!!!

The reason there is a difference in price between the 2 heads shown on that page are due to Valve size.
When using such large valves as they do on the most expensive heads, they have to change out all the seats. I also wouldnt be surprised if they had bronze valve guides.
TEA can do all of this also. it will cost more but they can do it.
As long as both heads use the stock seats. There shouldnt be hardly any difference in price.

this is classic!! A classic case of people not capable of doing their heads themselves who bitch and moan having to pay for someone elses knowledge who CAN!! who has spent YEARS doing only heads trying to make a living charging very nominal prices... lots of guys.. including Craig at GTP.. who has a pretty good rep as far as work goes.. NO shop is perfect... Do TEA heads work?? YES... do they make the most power on the street for the buck?? NO.. meaning are their more expensive heads making consitently more power.. has Craig been doing heads with the "fame" of powering some of the fastest F/Y -bodies LT1/4-LS1/6? YES again!! are there many other people who can get similar results who do heads? YES... if they don't want to charge for it then that is their business... if your too cheap to go with one of the industries best... DON'T.. that simple.. this who has the best heads thing has been TOTALLY BEAT TO DEATH..... HUNDREDS of times!! Use what works for you!! Personally a cam is more value on the LS1 than heads alone.. if you don't have to have the highest dyno numbers on the block then TEA is a great deal..if you want the fastest car on the block... YOU WILL have the most expensive car on the block... that simple guys.. knowing this list.. flame away..

I ONLY use GTP myself.. has worked great for me for years... not many 460+ RWHP 383LT4 NA combinations out there.. without titanium this and Billet that internals.. with the Felpro now its 480+

with a set of stage 2 LS6's getting ready to go on my Z06

Z-06 I hope your post wasnt a reply to mine? I was stating why there was a difference in price between 2 sets of gtp heads.Simple showing why there was a price difference.
I know some of Craigs customers have won some races with his product on their cars.
Do you think Brians cars havnt won races? championships? titles? cause they have.

But I also dont think they are the fastest out there are they? Have they beat MTI's times? Or ARE's
Craig does a great job I do not disagree,However so does Brian.

[QUOTE]do they make the most power for the buck? no?[/Quote}
I would say for the money TEA's make the most for dollar spent.The money saved by using TEA over GTP can be used to buy more mods.
Everyone doesnt have the unlimited money <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Most of us dont at least.so if there is a believed 5-10 hp difference (Between TEA and GTP)for 400-800 difference in price I know which way I would go.

Thunder Racing isn't the only place that sells GTP. Dual valvesprings that the TEA has as an option is the same dual springs GTP has for an option for $75. I think Thunder uses a different dual spring that requires machining.

NO ONE is an expert at everything so we PAY people who are good at what we are not to build an outstanding product that we need.

The point here is are people happy with the product they bought and did they get what they expected for their money.

I say its to hard to get a honest comparison. There is way too many varibles to have a dyno comarison (rear ends, air temp, other bolt ons, cams, elevation, etc..,) <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> But I would really like to know if its worth spendin the extra bucks on the GTPS. Although Raging Motorsport sells GTPs for like 2400 bucks (single coil springs I beleive). I bought a pair of CNCd heads from CNC used and I guess my numbers are pretty low. I only dynoed once and Speed Inc (is there dyno known to be high or low??) and I had some low numbers with a decent cam. With a 227/224 I didn't even hit 400, I guess if I played with it a little bit more I can acheive that number but the car still pulls like of Son of a BItch up top. Plus I only paid 1200 for those heads which is pretty cheap if you ask me. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

If all these cars were tested on the same dyno you might have a valid comparison. Its been well documented that there are differences in dyno's. Track times mean more to me than dyno numbers. There are many variables comparing times too. Driver, race weight, and car set up. This argument will never be won or lost by anybody. I say if you want to find out which car is quicker, line them up. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" alt="[burn out]" title="" src="graemlins/gr_burnout.gif" /> <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Personally I went with TEA for the price and the fact that most of their cars are over 400RWHP with the right mods.

Hey Fireball, aren't you running like 12.1 compression on those gtp 5.3 heads?? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> And don't you have a cam the size of New Jersey?? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> And your car has always been an anomaly. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I'm running that puny b1cam with about 10.6 compression on my gtp heads.

Long time. Hope everything is good.

418rwhp & 404rwtq

See Sig for details.

Stock clutch was stinking at the end of the dyno pull, so I think a few more ponies. I have the ATI dampner instead of an underdrive pulley, I would image that cost a few hp too. The car has mail order tuning.

I'm happy with the results.

steve...i agree with what has been stated. picking up a TR230/224 (or in that range) cam would give you a significant boost in power with your heads <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

I just put a set of TEA 5.3 stage 1.5 heads on (918 springs on them), no other changes to the car except the heads, lowering the rev limiter 100rpm to 6400 and putting the PE/RPM table 4% richer. My only complaint is the car is detonating a lot, I think the compression is a little higher then what I wanted but I'll work around that.

Not to make 'excuses' but I had to run the car a little rich to keep it from pinging at high RPM and still had 3-5 degrees of KR the whole pull that started when I floored it - timing was 18 at 4200 and creeped up to 23 at 6400, thats why the torque is a bit low. Excuse mode off <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Anyhow, 383rwhp with that little timing and rich a/f through FLP cats and a stock Z06 exhaust in a 80,000 mile A4 C5 (converter locked, made 372rwhp unlocked) with a 'baby' 216/220 525/532 114 cam isnt too bad. Anyhow, not bad heads for the money, when I get some time and get everything right I will be even happier..

This is the 'best' pull I had with the cam before the heads, picked up ~28rwhp. The real max hp is 355, the 357 is from the spike at the end.

Just wanted to point out one thing. Alot of people are running 5.3 head and not 5.7 heads. Therefore making more hp than one would if they just had a set of 5.7's ported due to compresion ratio.

Guys that are running 5.3 heads what octane gas do you run?
