SCE head gasket part numbers tell you the gasket type, engine family, bore opening and thickness.
- Style Code determines the type: CR=Vulcan Cut-Ring, M=MLS Spartan, P=Pro-Copper, S=ICS, T=Titan, 5=Accu-Seal Pro
- Engine Code: 2 digits. (There are over 50 engine families.) Searching within the website or catalog by engine will provide this information.
- Bore: 1st & 2nd decimal places of the Bore opening measurement. The whole number (left of the decimal) is assumed to be known.
- Thickness, 2 digits: 21=.021″, 32=.032″, 43=.043″, 51=.051″, 62=.062″, 72=.072″, 80=.080″, 93=.093″
