    Just to put this topic to bed, I’ve talked to 2 VERY reputable guys that I’m sure everyone here knows and respects and they both said these heads are great budget heads for a LS3 but not for our L76 engines. They both said that they have seen these heads on L76’s and tuned them and saw little to no gain in power. They both say you either need to buy something like Mast heads with the canted valves or get a company CNC port LS3 heads specifically for our engines.

    I don’t want to post their names on here because I’m downplaying a product and I don’t know how that will effect them or who would get upset but I wanted to inform you guys. Just have your heads ported for the L76 or spend big money on some Mast heads etc.

    Having said all of that I’m going to buy a stock set of LS3 heads from SDPC and send them off to have them ported.
