Default What head gaskets for 4.030 bore motor
I am wondering what head gaskets I should run with my 4.030 bore le1 headed motor. I was thinking about the GM 12553160 gaskets, but summit has them listed as a 4in bore. What gaskets would be the best choice?

Yep, Everyone I know just uses the standard head gasket or the Impala gasket. Plenty of room for .030 over.
