Dana,you may want to check wich power valve or valves you have along with the cam steps on the pumps,there are a LOT of combinations you can end up with if some one bench alters a stock carb,you may also want to consider sight plugs for the bowls(fuel level) and a check valve (summit) to protect the power valve from being ruined by backfire.An excellent book on Holley carbs is available from Dave Emanuel, s/a books I believe, will show you how all the circuits overlap and work together.
