Let me start with zero decking. To zero deck the 292 you need a set of custom piston $500-600. I'd go with Federal Mogul LPG pistons they will get you close to 9.0:1 and shaving the head will make up the difference. The stock pistons are 8.6:1 and the dish on the LPG piston is about half the stock piston. Let the machine shop tell you what you will need for oversize pistons. IIRC the LPG pistons are Hypereutectic and have a different expansion factor. Also zero decking will get you closer to 10.0:1 with the stock head.
On the Felpro gasket set get one with the 85001PT1 head gasket it is a step above the standard. It has additional sealing around the vent, and push rod holes.
If anyone knows the l6 head Twisted6 does, what ever he says goes.
Before you put the motor together you will need to know the deck clearance, combustion chamber CCs, stroke 4.76, bore size, and the CCs of the dish in the piston to calculate compression.
