Magnum 360 Head Gaskets

So I am planning my 360 magnum build and started to look for head gaskets to plug into my comp ratio calc - cannot find too many head gaskets at Summit, and most of the ones I do find are OEM replacements w/o specs like bore dia and compressed thickness

I need a proper head gasket for a magnum block to use with magnum heads and obviously I want all the dimensions and details too (is that asking too much?)

Not looking to spend $100 each for gaskets either...

Thanks in advance


oh my truck I run felpro 1008, I know many of dakota guys running these gaskets.
