I want to know if there is such a gasket with this Felpro #

1262-R

I know there is a 1262, but for some reason I think I bought one with an R. Lost reciepts??

The "R" might be for the coolant passages (reverse flow). Dont quote me on it though just a educated guess.

I already found out that there is a 1262 and a 1262-R. I have the r gaskets.

Thanks

So what is the difference between the regular 1262 and the "R"?? I'm interested as well.

The 1262 has a port size of 1.28 X 2.10
The 1262R has a port size of 1.40 X 2.25

I guess it is used for the r series heads or stage three ported heads.
My AFR's are port matched using the R gasket.

Damn! thats one heck of an intake port... would take a serious motor to need more than a 1262! Thanks for the info.
