Gasket choices 454 MAG

[sparky774]

Im rebuilding a 454 420 mag motor, using 088 rect port heads, standard bore 4.25 cylinders. Can someone school me on gasket choices here, i am going to switch to closed cooling but i am going to do this after i break in the cam so i dont have any unforseen issues with overheating, i will do this on the hose with fresh water. I need all gaskets but i am mostly concerned with intake, head gaskets, and exhaust gaskets. I am running stainless marine exhaust.

Could someone help me out here just trying to get an idea of what gaskets i should get or if i should just go with stock mercruiser gaskets

I suggest Felpro. Stock Mercruiser gaskets are stock GM gaskets.

No, on closed cooling you may select any head gasket, that is the on you are asking about, right?
