I'm fixin' to put the top end of my 97 M900 back together (cylinders, head, etc) and am wondering what type/kind of goop I should use on the aluminum base gasket. My Haynes manual said I should use some, but it isn't specific as to what type/kind. Anyone have any favorites? I've got black, gray, hi-temp black, and some old fashioned Permatex (both the black non-hardening kind and the rust colored kind that hardens). Recommendaitons?
Chris--I lapped the valves after cleaning up the heads, but I didn't know, nor has anyone or any manual mentioned lapping the head to the cylinder, although is makes sense. The studs are still in place. Seems like I'd need to remove them to get enough movement to do any lapping of those two surfaces. Is that what I would need to do. . . strip the studs from the crankcase? If I do that I think the Haynes manual says I'd need to replace them. . . yes? Thanks.
