IMO there isn't much extra to be had if you go +.030 or say +.060.

You must sonic test to know for sure. I have seen a few over .300" thick that would easly take a +.100 bore and a couple that are less than .200" thick. Most are around .225-.250" thick on the thrust but get down to .100 between the cyls. Id only go +.005" unless testing.

I would go 4.005 at first so if you have to rebuild the engine, you have another off the shelf piston size still left (4.030") without having to go to custom pistons ($$)

AutoTec pistons have a 4.005'', 4.010'', and 4.020" both 3.622, and 4'' stroke dish or flat top.
