The guide plates are from Hughes. The studs are 7/16ths and drilled and tapped by the machine shop. The guide plates stud holes are big enough to give adjustment with the 7/16th studs. The heads came from the shop, they are new heavy castings with plenty of meat. The guy that did the bowl work was impressed with the flow and no...I don't have any numbers. I can't wait to fire this thing up now.
