OK, now I know why we have a difference of opinion here… The TD-20 has a separate carburetor gasket with the two studs that mount to the intake/exhaust manifold. The TD-20 gasket is a simple carb intake with two holes for the mounting studs. In shape it looks similar to 1950’s and later carburetor gaskets.
The HD-25, on the other hand, has a carburetor that is integral to the intake and exhaust manifold. Everything is in one piece, so the only gasket is the much more complex intake/exhaust manifold gasket with all of those radius’ and ports. Check out the gasket 43-221 that Willy referred to, and you will see.
