  • 150 vs 200 heads

    What's the difference between 6G4 and 6G5 cylinder heads for late 80s V6s?

    Chamber volume (compression)?

    Heads

    Yes. The sides of the chambers can be deeper but also the center cup is bigger in diameter and it's deeper in the "smaller" motors. I have a pair of 200 heads if you want me to measure them or sell to you.
