Valve Clearance

#1 why would you choose a cam before the short block is together. you want as close to zero deck as you can get with the 383.

I had 1.848" compression height pistons in it already that came with my block when I bought it and it put me 0.090"down hole at TDC when installed them. I found 1.92" flat tops that will get me much closer to zero deck. I didnt think to measure my piston clearance before I pulled them out. Rookie mistake.
