Its officially Winter. Another small block build begins

This one will get a roller cam for sure. The 422 Indy headed engine in the car has a solid lifter cam and had been 9.40’s. (5.98). I will be freshening that engine too this winter and if the cam still looks good will be going back in. It’s a 650 lift with EDM lifters. Three years on it so far with zero issues.
How do you prepp a sb for roller? Do yoy tube it or do you use bushings in the lifter valley?
I havent decided yet about my cam.
