I agree here if it is a small bore and you have the Felpro 7013-R1 I would use it. The R3 is really not the best unless you are bored past .060. I have an NORS McCord and a Felpro R1 saved back for cloe to stock sized engines. The R3 was made assuming all engies were bored considerably and really are a poor choice for a small bore. I have 3 blocks that I know are all under .040 and several will clean up at .060. Larry recommends the R3, for the BF, but if a samll bore I would still use the R1. I have not used the newer composite gaskets on the market as of yet. Rod
