Head gasket help.
 

Guys and Gals, I have a 427 thats .030 over so its a 433cid bbc. I have a set of oval port 049 heads that are at the machine shop right now. I am having trouble figuring out the right head gasket and bore of the gasket. Any help would be appreciated. Thanks

What year is the block?

Re: Head gasket help.
 

Sorry its a mark iv 1973 454 block.

If the block does not have the three holes in the deck surface just above the lower row of head bolts, it is a "series cooled" block and would take something like a Fel-Pro 8180PT2:

If the block does have the three cooling holes above the lower row of head bolts, it is a "parallel cooled" block and would take something like a Fel-Pro 1037:

Hope this helps.
