Help with decking or not?

U show the end to end but the decks could also be sloped and or twisted
and it looks like 9.590 would be 0 deck ( unless your rods have been rebuilt- had the caps cut so shorter
closed chamber heads
you can try 9.6 and use the .028 gasket or if you have to go less and use a thicker gasket
remember some SBM cam with the piston above deck
you should be able to make it work
tight quench is better
The rods are new from the kit.
I was thinking have him square up the block. Decking to 9.6. My pistons have valve reliefs 5cc. They are icon 741. Just want to make sure i dont deck it too much. I plan on giving him the call tomorow to ler him know but trying to get all inputs in and do some research since this motor is bores and stroked.
