Just getting started on a set of 1972 j's, milled the guide down .200 and about to profile the guide. was there a long thread about porting j/x heads? I can't seem to find it. anyway, can the guide tail be removed completely? This will be going on a somewhat stock appearing 6 pack, intake has been deep port matched. I know aluminum heads would be much better but the 6 pack intake don't flow all the great anyway, plus the looks on their faces when they see they got smacked by a SB with stock heads is fun.
