air gap install, guide pins on deck!!!

ok I had everthing set, was just going to do the black rtv on the edges, now it looks like a pretty big space. The head gaskets have little tabs sticking out which Im sure are preventing the intake from seating down more, should I cut those flush with the heads to take that out of the mix, and the damn bolts I bought were too short, does anyone know what size intake bolts I need for this airgap edelbrock laying on a 340 deck, bolting into 318 heads. AHHHHH!! BREATH, RELAX,CLEAN UP THE RTV AND START OVER!!! HEY THOSE SIDE GASKETS MAY BRIDGE THE GAP BETTER THAN JUST RTV OR WHAT??
