5.9 Magnum

Factory Magnum heads are 62. Seems to me you should have better than 9.1. The factory gasket is .048.

My engine is not a magnum, its an LA

And for the record, not sure where the 9.1 spec is coming from, but I would take ANYTHING that the factory says something is with a grain of salt...cc it all and do your calcs then see what it really is
