any dyno results on the TF heads yet. A friend of my sold me his stage 3 pi heads for 450 cause he orders the TF heads, i want to know if he made the correct decission.

there is no way these heads will yield 50% more power but if I was in the market for heads they would probably be the ones I would purchase.

If i buy this 97 GT that im looking at, they are the only heads i would buy for it. And just be careful using stage 3 heads on a stock bottom end...you might have to bore the block out a bit to make it work. Just saying.

my bad that was stage 2 heads, so i quess no one has any dyno charts of d TF heads

There was one post on here a couple months ago and i think the guy got somewhere like 350rwhp or so. it was a real nice number.

I hope they get more because stock ported heads and added compression can get you that.

But you can port these out and use more cam than ported PI heads so you can get well over that. So these ported with some crower stage 4's or CMS stage 3 N/A cams would be nasty.

Should, just haven't seen it yet.

Yes, this was on a stock bottom end, and he wasn't done tuning yet. His tuner said he would likely be around 370-380. Atleast thats what i remember being said.
