    Would these be great heads for a stock 5.3? I got bad luck with the cracked heads sadly..

    Asked by: Jack18
    These heads are made to fit the early generation small block engines, if your engine is a LS series you will need this type of head - https://www.jegs.com/i/Chevrolet-Performance/809/12629063/10002/-1

    I am considering the 2169 ProMaxx heads for my 1959 corvette 283 SBC which has a 56cc combustion chamber. Is this head too much to consider for a slight performance upgrade while also upgrading to the CompCam 249-12-234-2 ? This cam is close to original.

    Asked by: josephB
    That head is for a 4'' bore block , the valves will have an interference issue with the 283

    Will the included springs and hardware work on a Hydraulic Roller block or would stiffer springs be needed? Cam wouldn't be too radical, ballpark 234 at 050,. 520-.540 lift 112-114 LSA. Doing a build on a low mileage Vortec roller 350.

    Asked by: B Hawkins
    As long as the lift does not exceed .575" it should work.

    I have a 1972 Chevelle with 350 engine. Can I use my original stamped steel rocker arms with these heads if I order them set up for flat tappet hydraulic cam? I am running a 350 horse 327 cam with .447" lift on intake and exhaust. Thanks
