    Default Differences between truck and Hummer heads

    Stumbled across a set of new-in-the-crate 6.5 heads. They are listed as coming from a center-mounted turbo engine. Are there any differences between these and the side-mount turbo heads?

    POSSIBLY

    Look at the angle of the intake manifold mounting holes.

    Screw a bolt in an intake mounting hole

    If they come straight out from the intake face they are standard pickup... If they are at 60 degree angle up they are van or hummer.

    Good luck
