Looking to do a Skunk 2 stage 2 head build. Skunk 2 stage 2 cames, valve springs retainers etc. Basicaly I have been reading about needing a min amount of compression to make it worth going with the stage 2 cam. What is the ideal min compression number that I need to shoot for to benefit from the stage 2? I ask this because I am planning on running my usual 50-70 shot of juice on the motor. I'm just interested in building a reliable good performing allmotor build and just having the juice on tap if I need for that extra punch.
