That means cutting the head while opening up the combustion chamber to maintain a specific compression.

That’s the glory of an RK Tek. Just call him and tell him what you’re after performance wise, what fuel you run, and what altitude you’re at. He will cut an insert specifically for you. It’s not some canned head that is setting on a shelf. He doesn’t have any inserts pre-made, he will cut your after he talks to you.
