12.5 compression for a blower is getting pretty high. Will limit the tuning window. Normal use includes o ringed block and receiver grooved heads or vise versa and copper head gaskets. SCE has some copper gaskets that have seal rings inside the gasket. You could use thicker heads gaskets to lower you compression. Check with Cometic on their MLS gaskets.
