Quote: Besides the rings, is it common to have bad valve guides that suck oil but still allow high compression #s? Last year when replacing the valve stem seals I noticed some valve stem wear, so I pulled the heads to take to the machine shop. 7 Intake valves had stem wear and one exhaust valve as well.
You mentioned earlier that you had smoking on decel. Vacuum created during closed-throttle decel could pull oil in thru worn valve stems/guides.
I've often wondered about rich-mixture/new rings/cam break-in too. Here's an interesting article on pistonring break-in. Probably some folks will refute it, but I think most of us could agree there is some valid info in there, and good food for thought. http://www.ntnoa.org/enginebreakin.htm
