Ed;
It's a little late for this now, but I always check my piston to valve clearance, even on my street motor which has a puny little 484 lift cam.....reason being, if anytime in the future I want to upgrade my cam or rocker arms or anyhting else, I pretty much know how far I could go without getting into trouble......
Also, when I build a motor, I keep records of everything.....Rod and main cap torque #'s,piston to cylinder clearance, ring end gaps,head bolt torque, part numbers of rings,piston,
oil pump,etc.,etc.....
It may be overkill, but when and if I need to go back into the motor to freshen it up or make changes, it saves me a lot of time and head scratching..............
