Cool this is why I like to just go straight to the Aluminum case. Already shuffle pinned drilled for full flow and opened up for whatever cylinder you want to put in there. I don't usually go over 90.5 or 92 thick wall. also clearanced for stroker. then I put a 78 in there. still bulletproof. IMO. Better more stable material (aluminum less expansion and contraction) My buddy got over 150k miles on a aluminum case engine.
It keeps the 2 halves of the case from "shuffling" or sliding back and forth against each other in higher performance applications. We like to do them when you get into cranks bigger than 74mm.
