HP potential for a 9.2:1 360???

Is it really possible to achieve 9.2:1 with stock pistons? I was playing around with a CR calculator and I think you would need .055 or less deck clearance, .039 head gaskets, and 65cc head volume to get there.
I also have a low mile 360 roller LA. I guess I should pull the heads and measure the deck. Always counted on around .080 with stock slugs. If this works out for you I may be following in your footsteps.
