Ok, 1039 is a composition gasket, the 1105 is a steel core laminate. I'm deciding between those 2, which one is best for my 400 block and 440-1 heads?

I'm gonna avoid the 1009, too many horror stories of them overhanging the bore.

But I'm also still wondering what is 'wrong' with the Mopar P4349559 gasket??



I am not posative but that mopar gasket is a 1009 felpro
I used the 1039 on my low deck with b1bs heads we used 1105s on a low deck with origanl b1
