    Typical smogger castings used from 1974-1980. Should have 1.94/1.50 valves and will be 76 CC chambers. Nothing special unfortunately. Sorry.
    JUST FOR CLARIFICATION

    I hate GMT900 trucks period.

      nothing special, and prone to cracks. they look like the heavier casting early heads (straight along the bottom side vs scalloped like newer lighter duty castings), but are actually lighter castings. they can be made to flow pretty decent though.
