Ok, thanks. I know someone looking at doing this, but I didn't know if it was worth the effort. His Edelbrocks are gasket matched with minor porting + cleanup work done to them,
IMHO, his money would be better spent having his current heads ported. If he were having to buy heads and rockers maybe then the Trick Flows may be the way to go. I haven't seen any numbers from the track from a Trick Flow combo that was overly impressive over known Edelbrock combo's.
