After 3 years of leaking oil, I am ready to commit to: Head gasket repair kit, Valve guides, and valve seals, plus new timing chain replacement while the head is off. Questions: Wouldn't I be better off buying a rebuilt head, which automatically gives me a "head gasket repair kit" (head, exhaust, and intake gaskets) then add timing chain renew? Engine 1992 has 141,000 miles runs good, not great, some power loss , Also would there be any benefit to polishing intake ports, or any other horse power tricks that could employed a this point? (replacing all vacuum and emission hoses will be mandatory.......thanks .......Rick
