Compatibility
Fits 2-barrel, 2-hole Holley-style carburetors. This is a smaller bore pattern than the 4-barrel square-bore gaskets (ALL87200, ALL87202) and the 4500/Dominator flange gasket (ALL87206), and is not interchangeable with them. This listing is for a single gasket; the same 2-barrel Holley-style gasket is also sold as a 10-pack under ALL87204-10.
