a lot of heads have this, use a good sealer on the studs, and grind them off smooth "after u tighten them" use to do it on my 600 horse 406 sbc.--no problem---bob
Those are a lot smaller than the last set I had. Its Normal. Most of the SBC heads have them too. As mentioned, use a good sealer NOT Teflon TAPE, use a sealing compound.
