I got the DIY kit, but he builds carbs too. The kit has what appears to be a modified Proform billet metering block (not sure on the manufacture of the block, but it looks like a Proform), 4 jets, 1 high-flow PV, 1 PV plug, 2 squirters, 2 high-flow needles & seats (130's if I recall correctly), and 2 30cc GFLT pump diaphragms. Everything you need on the carb side.
