L78/L89 Intake Manifold Gasket

[blackss69]

What is the best intake manifold gasket for a stock L78/L89 that has a blocked heat passage.?  I looked up and maybe Felpro 1211 with stock size ports or Victor Reinz has a nitroseal with the stock size ports.


Thanks

I use MR gasket 108. Trim the outside with a razor knife when assembled. The 1211 has a larger port openingbthan I like. Jeff

Same thing for SBC manifold gaskets. I utilize Paragon (Corvette specialist) for many restoration items as they and other Corvette supply houses are in tune with NCRS restoration needs.
