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

Felpro makes a gasket Part Number 519SD "SUPER DUTY" Compressed thickness is .054 The bore is 4.172, I know because I just used Two sets. The price is right around $60.00 a pair and I bought them from ROCK AUTO online. Hope this helps.
