Same issue here with 502 block, aluminum heads and stainless marine. The manifolds have already been clearenced. I have extra lower row outside bolts that I have ground off the top of the head. Since aluminum, I feel I need to keep the washer. Other than potentially causing a "rounding" head issue, any problems with this?
