My favorite back in my V-8 fourbarrel days was the Mr Gasket multi layer gasket and aluminum shim plate with a larger aluminum heat shield. It was a four hole and worked well even on an open plenum intake. What it was 4-5 aluminum plates alternating with gaskets. The only thing you had to be careful of was torque as the multiple gaskets allowed you to really screw up a base plate if you tried to overtorque things. I never had a boil/vaporlock problem after installing one of these. -- Mark Price Morgantown, WV 1969 AMC Rambler, 4.0L, EFI, T-5 -------------- Original message ---------------------- From: Todd Tomason <jayscore@xxxxxxxxxxxxx> > When we removed the factory two barrel on my son's 78 Matador, there was a > 1/4" spacer under the carb.
