1995 454XL V-Drive with Rochester Quadrajet. I removed the carburetors to clean up the intake manifolds. The port side has a gasket and looks like a half gasket, the stbd has just a gasket. Carbs were removed last year for rebuild by mechanic who is now gone so I don't know what was originally there. My parts catalog (TECM 556) only shows the Holley with square bore. Do I need a wedge (CRU 97122) ? I also have seen 7 degree and 8 degree wedges on the net. Would I put a clinometer on the intake to measure angle??
