I always thought a lot of valve train noise was normal for BBs, though mine always seemed excessive. Decided to pull the valve covers and poke around today, I'm a novice and learned everything I know from here, youtube, and books. I noticed the roller rockers have quite a bit of side to side movement, over .035" worth (that's the largest feeler gauge size I had) but it's pretty close to being that measurement. When I first built the car I didn't even know that was something that needed to be checked. I read the side to side play should be between 0.015 - .030 while getting the tip of the rocker as close to center on the valve stem as possible.
I'm running Comp Cam magnum rollers with a stock shaft, stock hold downs, and stock spacers. Besides the shims is there anything else I should consider upgrading replacing to correct this. Engine is a 383 with 440source Stealth heads.
