RE: CM 870 Overhaul Advise
Also get new oil pump and shim the oil pressure regulator with 3/4” of shims.
I superglued washers the size of dimes for my shims.

Your cams and rockers will tank you later. So will your rod bearing.

To do a proper rebuild on a cm870 is not cheap.
Don’t cut corners!
Also rebuild your fuel management system and do an injector leak test with your rebuild.
At the very least take your ifsm apart and clean everything well.
