I bought brand new still in the box trickflow twisted wedge heads for $850. They are the street heats but I have comp springs good for a .630 lift. Few questions. If I mill my heads from a 61cc to a 58cc (which would equal 10:1 comp) would I have even more pvc to worry about? I'm going with a custom cam from Ed. Intake will be street heat intake with stage 1 port to match heads from foxlake. How will this bad boy run?
