cometic head gasket question

[670 of 4993]

i'm ordering head gaskets for my 306 and encountered a problem on summitracing when ordering. There are two identical gaskets (.030 over, .040 thickness) but different part numbers. One is specified as svo round bore and the other is non svo. What does this mean? are the gaskets bank specific?

Those are two differenet gaskets. They are not bank specific.

yea, i realized that the svo is an aftermarket block with 4 b old mains in the middle journals. So i went with non-svo gaskets
