I got the +.1 pushrods today, so I'm ready to finish off the valve train and button this engine up. I was wondering if anyone has feedback on adjusting the roller rockers. Sounds like the most accurate way is when the engine is hot and running (does not sound like fun) but I'd like to get as close as possible before hand to limit the mess.
I realize you need the lifter on the bottom of the cam lobe to find zero lash, and you want to adjust them with zero preload on the lifters. But how can you tell how far to tighten after the zero lash is achieved. Instructions say 1/2 to 1 turn. I've gone 1 turn and still have pretty loose (a noticeable sideplay) on idle rockers?
