I am leaning towards a 34mm bore as a compromise situation. This will reduce the wall thickness from 4mm to 3mm.
Can you elaborate on your cracking problems?
The spacers I removed from the engine after 22 years of use were fairly degraded, cracked and flaky at the head end but were still air-tight.
