btw, the used and abused 8553PT gasket thickness is right at .050" on the fire rings. I think if I use 8553PT again I might spray them with something to help seal. Don't want these ******* leaks again...

pistons must be close to zero deck to be pumping 185-190psi 4 years ago (that was cold too). magnum chamber, i'm guessing it's the Mopar Purple cam 268/272- .450/.455 lift.

Not sure where you're located, but if I were you, I'd wait for a half off day at Pick-n-Pull and grab a 'new' 5.9. Every time I go, there are plenty to choose from and on half off weekends, you can pick up a long block for ~$100. Most likely, it'll still have a crosshatch and be useable as-is.

That block you've got isn't worth the headache IMO, when replacements are so readily available and cheap.
