116.1? So they're adding material to the head?

Higher compression on a turbo is not generally considered a good thing. Get a gasket sized to keep the stock CR or thicker and add more boost... the minor bump in CR isn't going to gain you any noticeable increase in power, but the 5 extra psi of boost you'd otherwise have room for would.

A cast iron block that's seen over 20 years of service??? NO, they warp more than enough to be out of spec and cause major sealing issues... it doesn't take much. Why do I even bother if people aren't going to listen... hell read the damn manual.

Do as I said... get a MACHINIST straight edge (it's a precision tool) and use feelers to check the gaps (there WILL be gaps); If it's out of spec, pull it out or if it's not too bad go with a composite HG.
