I performed a piston to valve clearance on my 383 today. I don't think I need to go through the steps, but one thing I did I'm not sure of if it was right or not.....did I need to pump the lifters up before doing this check? I ask because I didn't pump them up, just put some assembly lube on them and performed the check as normal. Not sure if with the lifters pumped up how much it would affect my calculations.

Pistons are 2315's @ 0.005" in the bore, XE268 cam, I calculated .1755" of clearance NOT using a head gasket, just snugged the head down to hold it in place.

Anybody think I messed up by not pumping up the lifters beforehand?
