people using GTP heads,please read i know all the hype surrounding these new heads( PP,TEA,Absoulte...), but i know that it is hard to beat GTP heads on power . can you please post what kinda of power and track results you are having with GTP stage 2, 2+, or stage 3 heads. i have talked to graig(greg?) @GTP,and the dude knows his stuff and is an all around genuine person. props to GTP

Mine were proven to let oil past the bad guides they had in them. He would not make good on it. So I'm a little bitter about that. He actually looked me in the eye and told me the guides weren't bad when we had them apart on the bench and you could feel how loose they were in there.
IMO, other heads (AS, PP) are capable of making the same power, and in some cases more power than GTPs. GTP cars have seemingly always ran well at the track, and it seems there are alot of 430-440 RWHP GTP headed cars around. The major advantage that AS and PP have is cost. GTPs with dual springs are ~$2400. You can get a killer set of PP "LS6" or AS heads for ~$1700 or less.
Looks like the price of the stage 2 GTP with dual springs has come down from the $2899 it was last year to $2499
I don't recall see much posted about results with GTP for the last few months.

I have used three different sets of GTPs of my car with various setups and have had more than excellent results with them:
1) GTP stage 2 heads (more like a GTP stage 1 now), mild TR230/230 solid roller, 442rwhp/418rwtq, 11.16@125 (1.66 60')
2) GTP stage 2 heads, TR240/236 solid roller, 460rwhp/418rwtq, 10.59@128.60 (1.43 60')
3) GTP stage 2 heads, TR230/224 hydraulic cam, 442rwhp/410rwtq, 10.88@125.5 (1.51 60')
GTPs are a little more expensive than some of the other cylinder heads out there now. However, in my opinion, you do get what you pay for.

I believe you would be paying for an over priced, out of date head. Absolute has been on the forefront of R&D and has come out with some very nice developments latley. I myself chose the Patriot heads because there is nothing wrong with them. They make excellent power. When Patriot came out, it forced other vendors to drop there already overpriced heads down to a liveable price. GTP hasn't caught on to this obviouslly. You do get what you pay for, but just because you shell out for an expensive part does not mean they are good. In retrospect, there are way to many vendors that are putting out heads that are much better than the GTP's for much less money. Personally, if you are paying over $2k for a set of LS-1/5.3 style heads, you are getting ripped IMO. There's just way to many proven heads that cost less and have better quality. There is a limit to the "get what you pay for" thing.
I had speed inc. put a set of stage 2 gtp's on my car along with a 224/224 581 581 cam but the tq numbers are wayyyyy down. I'm still trying to figure it out. Thinking it may be the yella terra's or porting of the heads losing velocity.

GTPs are proven to perform, they consistently post nice hp#s, awesome track results and so on.i do not have doubt in my mind that they are one of the best(if not the best) heads on the market. i have yet to see the cheaper heads post the track #s GTPs have. and i am not talking about dyno #s,because to me that isnt **** unless you can back it up with track times. i am not trying to be rude to disrespectful, i am just asking for people to post munbers and nothing else. i do appreciate the help,but i am not asking for opinions.

GTP heads are pretty good, I would say that Craig's heads are top 10% heads for sure. I had a set of his early 1998 heads back in the day and went 11.5@116mph with them back in 2000. I've seen some very objective testing on his heads and other heads and his heads did very well. Some of his stuff from a few years ago had some oil issues but frankly that was a small handful and that all turned a corner. He would be one of my 5 choices if I was in the market.

Far too often people claim things are overpriced when in fact they simply cant afford something of that quality level and would rather bash it or try to compare a less expensive product to it. Im not saying everything that costs more is better but a good majority of higher priced items are superior to their low buck competitiors.
