What carb gasket

[downsr]

What carb gasket for small block rpm air gap dual plane with a 750 holley. Intake came with a gasket that went across the divider on intake.Is everyone using a 4 hole or open gasket

Mostly use the large open hole. Use the 4 hole if the manifold has the dividers for the separate holes

It's not really going this make a difference. Thickness is another story. Ether for heat insulating issues or a possible height issue.

Mr gasket 54 is what I use. They work well.

Mr Gasket 55 is the large hole one with all the dividers.
