If I've had a late night in the shop when I start out the next day I may repeat my last step. Ex (torquing heads, main studs, rods if I used a torque number). It only usually takes 10 minutes and is well worth the peace of mind. When setting valve I mark each rocker with a magic marker as I set them. After spending hours getting my rocker geometry set exactly how I want it I take an engraving tool and mark each rocker so it goes in that exact spot EVERY-TIME they are removed and replaced. This really helps at the track when rushing around.
