re using main caps

[kilroy be here]

how much should I mill off a set of used splayed caps before I fit them to a different block and then have it line honed??

I would have the machine shop cut the caps with a cap grinder then fit the caps to the block by milling the outer step. When the center 2 bolts are tight there should be between .002 and .004 between the block and outer main cap step.

I agree unless you are experienced with installing these caps have a machine shop that has experience installing them and use a milling machine to drill the splayed bolt holes not the junk drill guide that comes with the caps.
