I'm new here, Hello everyone. I have put together a .060" 427. factory steel crank, a '78 454 block casting 361959, with 049 heads 2.19 and 188 valves, Trw 2308af pistons, and a Holley strip dominator intake. I'm worried about over heating, I'm using a felpro 1037 gasket and it only has one coolant hole in the back of the gasket but my block has two, so one is covered up. When I ordered these I give them my head and block casting years, told them I wanted stainless fire rings and this is what they came up with. This is my first "Big Block Endeavor", any information would be helpful.

Thanks, J. Mink
