This explains the mastercraft kit if still available. Post number 68 has the part numbers. I did nothing other than swap the banjo fittings from the back to the front. My steam tubes were completely clogged so I just cut the tubes off leaving enough to attach a hose with some clamps. The hose that goes between the head fittings is one size smaller than the hose that dumps into the riser. Just take the fittings with you to match the hose and clamps. About 3 bucks spent at the napa parts store. I used rtv to install the fittings and swapped the hex plugs from the front of the head to the back. If the bajo bolts are fubar when you pull them you can get them at any napa or chevy dealer. Just order parts for a 94 camaro or vette.
