Hey Terry, did you have any piston to valve clearance issues with these
heads? When I asked Hughes about using the R/T heads with my cam(HER1828AL)
they said with the R/T heads they weren't sure, but there wouldn't be a
problem with the stock heads(which there wasn't). I was just wondering with
the R/T heads being a different design and being available with the larger
valves if they were just a bolt on deal.
