Pat My problem may be that these roller tipped rockers are evidently for vortec heads. When I ordered them it said self aligning/ vortec. Is there a difference in angle on the vortec heads or something ??
I figure'd they would be basically the same as my swirl ports? They were the only self aligning roller tips that they had. I dont want to go through the hassle and expense of putting in guide plates at this point.
