how about these heads?
anyone have any info on the GM performance phase 2 heads( #12480034 ), supposed to be the highest flowing stock? was wondering if these or a set of vortecs would be better, time to upgrade from my s/r torquers, basically stock castings with bigger valves.

Blue,
I am thinking of using the same heads on a 383 motor but they from what has been repsonded back to me, they may be too much for a milder (300ish HP) 350. If anyone can clear this up for us then let me know. I amsticking with the 5 speed and have no intention of putting more than 350hp in front of it. All I am lloking for is a mid 13 sec car.
