Carburetor gaskets
-
Typically the longer the distance from the throttle plate to the intake valve the more torque can be made. A 1/4 inch may not be felt by the driver but it may be measured if on a dyno. If you can make or by the gaskets I would put it back to the original gasket stack.Matt Matthews

I was advised that carb gaskets from a Ford 300ci six will work. I bought some( part Fel-Pro #60269, but they are thinner than I thought. Has anyone used these to mount the WA-1s? I look at them and it appears that two above and below the shield would be about right. What's opinion?

If you do not want to run gaskets, some people use a baklite spacer from a Chevy Six. They are about 1/2 inch thick. The part numbers are Delco 3692799 for '50 to '59 235 cid Chevy which has 3" spacing. The other spacer is Delco 3692797 which is similar but for the '34 to '53 Chevy and has 2 3/4" spacing.
The supplier is Chevs of the 40's.

Thanks Mars, I have no problem with the gaskets except they need to add up to a half inch top and bottom on each carb. I am curious, however, how well a hard bakelite will seal the carb from the manifold. Do these Chevy insulators require a gasket sealer(Permatex)?

Mine has 1/4" gaskets above and below the heat shield. Paper gasket with a nice
plastic grommet around the bolt holes to help prevent overtightening. No idea on
a part # tho. I just measured mine and it seems a tick less than 3" bolt spacing.
I'll check it better tomorrow. The reason this interests me is that with the
Clifford head being thicker (2 3/4") mine has 1" extensions made from exh. tubing
to level out the Twin-H air cleaners. It now occurs to me that I could jack the
carbs up with a 1" spacer/insulator and do away with the exh. pipe spacer between
the carbs and air cleaners. Hhmmm -

Yes, you will need to use a gasket on the top and bottom of each spacer. -
I have these Ford gaskets previously stated. Three of them stacked comes to about 1/2 inch. Fine so far. But, now I see why there is only one gasket above the heat shield... The manifold studs may be too short to accomodate all three Ford gaskets. Next week I'll see for sure.
