heat cross-over passage

What do you all think is the best way to block it? Is there possibly an intake gasket to do this? I've got a 1965 273 cid.

I have seen intake gaskets without the cutouts in them but I just use a piece of aluminum flashing like you would on your roof , cut it to block off passage and glue to head. put the gasket over them and torque them down. I have used this for years without any problem or burn thru

A long time ago I filled a crossover with Hi Temp RTV........... LOL, it still is plugged solid.

If it has the stock iron manifold, the steel gaskets are made with the crossover blocked. If not, then Fel_pro makes one, or, a piece of tim works too.

Either way ya win.
