BUT... as surface finish is a problem of concern for metal faced gaskets (ie: MLS, copper, etc), why don't you just use the Fel-Pro Performanc BB head gasket #1009... fiber faced, ant-istick coatings, with stainless steel armor that warps around an internal pre-compressed wire ring... this is bullet proof... long lasting and race proven! The internal wire ring is the same concept/design as commonly used for diesel engines (with high CR such as 16-21 and up).
