Mind if I jump in? I have an extra stock 5.0 upper/lower intake that I thought about porting. Only thing is, hole on upper number 8 cylinder has a gash in the rear corner about 1/16 deep and an 1/8 wide. How much can I shave off without ruining intake? Could I possibly shave enough and use a phenolic spacer? Car is '88 vert, still SD. Thanks.
