Ok, last week I did this with MTI heads.

That price for the TSP PRC 2.5s are killing me.

Or AFR heads and the price........my wife will kill me lol

IM seeing some PRC being order, but Im not see any dyno number coming out they. Only a week left in the sale

A better question should be how much RWHP and TQ would I be losing from between the to heads with my TR224 cam

I have a week to decide

 

Get the prcs can't beat the price and the performance is very close. There should be a few dynos with this heads I've saw a couple!

 

With the TR224 .56X lift grind I believe you want a head that has strong and low and midlift flow numbers. .600lift numbers don't mean a whole lot with this cam. The AFR's really deliver here and combined with their small port volume 205cc, they make a killer combo. My Patriot 5.3's flow decently well up top compared to the AFR's etc., but they are really strong from 200-500 lift with a 214cc port. I'm contemplating going with cosmetics, degreeing my cam and getting a better quench. 8-12rwhp left on the table there. Dump the cats and shoot for 430rwhp on a lil TR224.

If I could do it over you bet AFR's milled with perfect quench would be under my hood!

 

Phil...

I've watched you torture yourself over this decision for what seems like an eternity now in ten different threads and on at least two boards (that I know of!). If you would have been working overtime all that time you could have taken your wife on vacation AND bought the AFR's! (problem solved)

Just buy SOMETHING.....I can't take it anymore

Call me at AFR...perhaps I could enlighten you more than you already have been....I would like the chance to speak with you personally. I think all the heads you have been considering have something to offer, but of course I'm a bit partial to a few of the unique features the AFR 205 design offers...

Good luck....Your head must be ready to do this

thats great.
No doubt in my mind the afr's will make more power with the question you asked, however, here is the next question you have to ask yourself.
If I buy the AFR's for 2150 vs the PRC's for 1450 there is a 700 dollar differemce. For 700 dollars I could sell my LS6 intake and TB and add a fast 90/90 setup. Will I then make more power with the 2.5's and 90/90 or the AFR's and LS6/ported stocker?
Why your there why dont you upgrade the cam a little?
Do something with a faster ramp rate maybe a 224/228 581/589.
If I were you and on a tight budget i would do the 2.5 with the fast 90/90 and add a little larger cam.
If I was someone else with a larger budget I would do the AFR's with the 90/90 and a new cam.

 

Do it right the first time and get the ARF's. I was thinking about getting some PRC's or MTI's and yes theyre great heads, but how long would I be happy with em is the question.

 

I love this guy!!!
Tony your the He Devil. If I call you, I know Ill buy them. I think Ive been trying to convince myself out of buying them

Im a government employee so I dont get overtime. Now can I buy another brand heads>?

 

That's how I'm thinking. Everything I buy for my car that isn't the part I really wanted bugs me. For example: stainless steel headers instead of my jet-hots. (not as bad since it's not a performance thing), Yank PT4000 instead of TCI SSF (or even a Yank SS series since it's a daily driver), putting money into a rebuilt 4L60E instead of a nice, solid, not gonna break it TH400 and maybe even attempting to make a gear vendors OD fit....

I just bought an LS6 intake manifold so as not to horribly restrict my cam and am already realizing that down the road I will be ripping it out so I can get a FAST 90/90 setup. Not the same thing since I don't need the fast intake just yet, but you get the picture.

If you can swing it go with what you want and know is the best the first time and never have to worry about what you 'could' have done.

 

Well said and I couldn't agree more....

I just bought my third (and LAST) 3/8 drive impact gun. The two others that I bought were cheaper and of course promised close to the same amount of torque output as the one I recently purchased (the first was a joke....the second wasn't much better). I bought the first two because it killed me to pay $250 for a tool that I could good get for less than half the price that promised close to the same results (on paper). Well low and behold I just dropped dime on the $250 version and it simply rocks....almost blows away the 1/2 drive unit I have and is half the weight and half the size! Moral of the story....I should have bought the "more expensive" impact gun the FIRST time because when the smoke cleared I actually almost spent twice as much....

Anyway....kind of a funny story I thought I would share with you guys. Anyone in the market for a clean, slightly used 3/8 drive impact gun?? (I've got a couple of them!)

Regards,
Tony M.

And Phil....It's been painfully obvious you have been wanting to talk yourself into something else!! Call me....you won't regret it

 

I just got my AFR225's and man are they nice llooking!!! If they perform half as good as they look, I'll be in great shape (and I'm not just saying that because of the $20 that Tony Slipped in my pocket )

D

 

I would go with the 60cc AFRs and save up for the FAST 90/90 setup

PRCs are great but I'd get what you really want from the get go

 

so how do like your ingersol Ti 3/8 gun? I love mine

 

man,i gained 47.4rwhp going from the LG-x2 cam to the x3 cam and swaping from my old ported heads to the afr 205 ported heads. i was told the x2 to the x3 cam is only worth 8hp,so that means i got near 40hp from the afr's. remember,the gain was from a ported head to the afr ported heads,NOT stock to afr's. i also gained .5 and 7mph in the 1/4mi on a slipping clutch. WHATS THE PROBLEM BRO? buy afr's and be done.

 

Don't worry they will....LOL

(And I told you to keep quiet about the money!! )

Brent....The Ingersol is KILLER!
(I know youve got a couple of "dead players" in your tool box as well! )

Tony, I think AFR heads are about the best out there, but that's not a fair comparison. We have dynos of the PRC heads and they pick up close to the same amount of HP and nearly as much torque as the AFR 205s. Plus, they are based on the GM casting, which we all know is utterly inferior. How else would LS1s with over 150k miles still be running perfectly fine? <-- Sarcasm.

Phil, if you aren't going to spray huge amounts of nitrous on your engine or run loads of boost, the PRCs will be fine, especially for the price. Hell, for the amount of money saved, you could buy a nitrous kit to go with the PRCs and spray a 150 shot (which won't destroy stock heads because of their inferior deck thickness) and you will wipe the floor with the AFR headed car you would have had.

But, if you have the money, then this isn't an issue. Buy the AFRs because it is a better head, and you'll pay for it. If it is, then the PRCs and nitrous is a better value.

 

The Moral of this story is, you get what you pay for!! Bite the bullet, Ouch!!

 

So the determining factor, more often than not, that decides how fast you will go is..........................the depth of your pockets.

 

Isn't that prety much true with everything??
