You can get ProComp's, pretty cheap, i've got a couple sets in stock but they have the vent holes in them. Ron Owens may have some in stock w/o holes. Got a question for you though. Are you running conventional roller rockers and stud gurdle, or Jessel type rockers?? I don't know if the ProComp's will fit with Jessel's. I can take a set out to the shop and check for you. They do have a thick billet rail.
