Just had mine on the dyno,382/362 at the wheels. The heads are stock out of the box with a Ai 223/230 cam. It's also on stock 350 with 122,000 mi. More power to come when short block goes boom.

I just found this post over on the vette forums, This is the first negative thing i have hard about them. I got more parts in for my car i expect it to be together by the end of the year.
Just wanted to post my experience with the Trick Flow 21* heads I put on my 94 this summer.
Performance wise I was very dissapointed. My Vette ran a best time of 12.4 @ 112 mph before the install with the stock heads. I have cam, headers, gears, converter, etc. Motor is stock bottom and cubes. After install ran a best of 12.2 @ 112. Nothing else changed, 60', 1/8 mile times all the same. I even had the PCM retuned for the new heads through PCM4Less.
Installation was a pain as well. The dowel guide holes had to be drilled out because they did not match the dowels on the engine. The push rods rubbed up against the heads even with the longer pushrods Trick Flow recomended. The casting flash in the ports was unbelievable. For the money and results I have seen else where, I should have taken my stock heads and had them done by LE or AI. I say (JMO) if you are thinking of getting these heads do not waste your money. If you did buy these heads and had a favorable experience please post and let us know. Thanks!

When I installed the 21* heads, I did notice that the pushrods rubbed the intake runners with self-aligning rockers. I purchased a set of guideplates and NSA rockers and didn't have any clearance issues. The intake runners are slightly larger than stock, and I believe that Trick Flow designed them for use with NSA rockers.
