    Manufacturer's Part Number:
    10141280

    Suitable for towing, the Chevrolet Performance Big Block Chevy L29 Vortec Cast Iron Cylinder Head was used on 1996-2000 GM trucks/vans/SUVs with 7.4L 454 engines. Small 99cc combustion chambers allow the compression ratio to be raised one full point over most stock 119cc chambers & large oval ports flow better than other factory oval port cylinder heads.

    What is combustion chamber size and what are intake / exhaust valve sizes? Any changes to intake & exhaust port runners? How does this head compare to GM 10141279?

    Asked by: rrrrob
    Chamber volume 100cc. Valve size is set up for 2.065 / 1.72
