ENGINE GURUS:my 355 build,opinions on head gasket

[bosephus]

Here's my build:350 block bored .020 over,sealed power H345NP hyper flat top piston with 5 cc of valve relief,stock crank,stock rods resized with ARP bolts,lunati roller cam with .535/.550 lift and 231/239 duration @ .050 lift.,Heads are AFR 180,1.5:1scorpion roller rockers.My deck clearance measured out at .036. I have both a composite(.041 compressed) and a steel shim(.015 compressed) head gasket.AFR says I can use the steel shim gasket but I would probably have to mill the heads the next time they came off.Would the quench/squish be too much with the composite gasket(.036 deck + .041 gasket)?Compression ratios would be @9.97:1 with the shim and 9.41:1 with the composite.I dont want to have to mill a brand new set of AFR heads to change a head gasket but I also dont want detonation issues either!Any advice would be appreciated.Thanks
