My buddy and i are in the process of rebuilding a top end and our goal is to have around 200-215 lbs compression. It's an 88/89 265 cylinder ported with a fresh bore and piston, it has oem crank long rod with 86 style piston and spacer plate. its most likely getting a new cool head with interchangeable domes.. So how do we figure out what dome and spacer is needed? I know we need to know the deck height and check the squish band afterwards but it's been so long I don't remember the exact process.
