so i have a ls1 block that i'm goona put a eagle stroker kit into. what all do i need to do to prep the block. like sanding casting flash (where) and stuff like that. i'm gonna get it bored just a hair for the new pistons. when the guy does this does he need to align hone the mains? if so will i need new bearings? the crank came with bearings but i'm not sure how much they take off if the align hone the mains. what else should be done?
