Anyone have a flow sheet on non-ported LT-4 heads?
If anyone has this info, I would really appreciate it. GMpartsdirect is selling the LT4 heads for $615/head, fully assembled, so I was looking for a flow sheet to compare them with the AFR heads. thanks a bunch.

Check on www.ws6.com and click on the links section. Go to David Chernicoff's blown t/a all the way at the bottom. On his website there is an interesting comparison between different heads. Hope this helps.

Thanks guys, that helps a lot. Hey, Doc, could you elaborate more on the $300 statement. Is that per head or per set? Where, and what kind of heads. Thanks. Always looking for the best deal. I only currently have 1200 to spend due to tax return, but I guess I can keep saving if there is a better deal out there.

Per set, you can find head work places for less than that, fully rebuilt, but I have no experience with "budget" head stuff. I payed around $1500 for heads, fully rebuilt, helicoiled (dont leave home without em), etc

I found only a cam comparison, but thanks, anyway. I think I like the LT-4 heads. I like the fact that they're factory GM.

It used to be under the dyno results page. The link doesn't work anymore(I just checked). Lucky I copied the info when I first saw it! His stock lt4's flowed, intake/exhaust .100- 56/47 .200-119/102 .300-179/140 .400-218/164 .500-241/176 .600-232/182 Then he had them ported by gtp and got intake/exhaust .100-66.9/56.7 .200-137.5/112 .300-193.5/148.4 .400-236.3/183.7 .500-265.5/198.9 .600-280.2/208.1 These heads were done a couple of years ago. I've heard that people have not been getting good results from gtp recently. Hope this helps a bit. Sorry for the bad link.
