What i have is a 6.0 iron bored .040 using stock rods n crank n pistons are flat tops. Machinist said from his calculations the piston tops come above the deck .02 (this normal?) , heads are 243's plan on milling. 010 to clean them up n bump compression just a tad bit. Running a 224/230 .604/.609 lsa 112 and planned on using stock lq9 head gaskets. Whats my comp ratio gonna be? Any issues that stand out on this setup?
Thanks in advance

Maybe this will help:

And also, try posting this in the gen 3 internal section. This isn't advanced engineering.

Here is a compression ratio calculator. Just enter your specs and youll have your answer. Also check for piston to valve clearance.
