    JEGS Cast Iron Remanufactured Vortec Cylinder Head has fast burn combustion chambers and high-velocity intake and exhaust ports. These heads can be mildly ported and milled up to 0.040'' and require a Vortec-style intake manifold, modifying the heads to accept early intake manifolds is not recommended. Assembled with premium parts such as manganese valve guides, stainless steel valves and chrome-moly retainers. Heads fit all 1955-Present small blocks except LT1/LT4 and LS1-style engines.

    Features: 

    • Fast burn combustion chambers
    • High-velocity ports
    • New Valves, Springs, Locks, Seats, Guides, Retainers, Seals and Studs
    • Made in the USA

    JEGS EZ Kits are designed by JEGS professionals to ensure that you get all the correct parts you need.

    Would these heads be a stock replacement on a 1992 k1500?

    Asked by: Travispatt2
    These heads are currently not available. These should work for your application - http://www.jegs.com/i/Chevrolet-Performance/809/12558060/10002/-1

    will these work on 1989 5.7 ?

    Asked by: leo13
    This will bolt to the '89 block, however, the '89 intake will not work with it.

    I'm building a 355 sbc that has been zero decked with flat tops. With 64cc chambers I get 10:3 compression. Is that too much for street motor on pump gas? What cam would you recommend? 4200# car with th350 2:73 gears.

    Asked by: 72monte
    10.3:1 is not too high for pump gas 91 or 93 would both work fine. As for the cam, one form the "Extreme Energy" series from Comp Cams would be great.

    Will these work on an ‘87 gmc 350 w fuel injection?

    Asked by: CalT
    Not with the factory intake. you will have to use a carb intake with a tbi adapter plate in order to use these heads.

    Is the .475 valve lift limitation because of coil bind or retainer to valve guide clearance?

    Asked by: Mike1971
    The limitation is due to a combination of the spring and valve guide clearance.
