R11 and R2 and PB on felpro head gaskets mean anything
Got some different felpro head gaskets here. One set has PB on one end and R2 on the other.
Another set has R11. Do these numbers mean anything to anyone other then felpro?
The R2 ones have more round cylinder holes where the R11 ones have a lower circle and the uper circle has two points. Not well defined points. Just very vague where you can tell its not perfectly round. Maybe that straightens out when they are torqued.
