Rochester 2bbl w/ heated base

[AcampoDave]

I pulled the carb for some maintenance today and noticed the base gasket was getting pretty oxidized from the exhaust heat ports in the intake. I have read where guys tap and plug those two ports but I'm just not into pulling the manifold at this time. I was wondering if perhaps they made a base gasket that would block those holes or perhaps there was some other old school quick fix that you guys might know of to block those 2 holes. I saw some gaskests online that appeared to be designed for manifolds without the heated flange but they look to be more or less paper, while mine is more like an exhaust manifold gasket.
