Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .

Just wanted to ask a question which will barely change the subject of the thread. But I just discovered a set of Comp Cam 928 Springs brand new in the box with 10° keepers and retainers. 1.88 installed height, 170 seat pressure. 356 spring rate good to .630 lift. Can these work with a .512 hydraulic roller? Asking for a friend.
