Je pistons

Just 2 quick thoughts. 5/16 rod bolts are inadequate for a long stroke engine, so those rods with the thin bolts should be avoided. 3/8 minimum!

Running a thick gasket to change compression is bad news, you lose the ultra important squish band. The piston bowl is where compression ratio changs should occur, or in the head chamber volume. With decent rods you should be able to run a good piston protruding into the gasket itself. Squish makes vast difference to det avoidance on biggish bore cylinders.
