Exploded the engine, nothing obvious, wrist pins look fine. Dropped off at machine shop, possibly cylinders out of spec, bad head gasket,.. Pending cleaning and measurements next.

Did you check the piston to cyl play ?
,take pics of the rod bearings and crank journals , I'd have the rods resized ( best done by a master level )

At the machine shop, they will check all the clearances.

Does anyone engine specs, Crank/Cylinder/Rod bore/Crankshaft housing bore dimensions, torques for these, Cylinder wall clearance? Or are the answers in the H20/H16(R) engine service manual?

Yup … You can find everything you’re looking for in the ‘Service Manuals’ section of the Tech Wili - Lots of overlap in the various service manuals listed there … just pick one.

Since you have a Low Windshield SPL311, you might also find the downloadable quick reference (full-spec) sheet below useful:

You can tell when the crank bearings are put in & plastic guage the bearing play , usually no probs.
