I've got a 383 with a Comp Cams XE268 and I'm running close to 10:1 with flat tops. The cam lift is in the .490 range for the intake and a little less for the exhaust. The only problem arose when a valve guide seized and held an intake open, but that's a freak accident. I have to use premium gas. As above, I would recheck your compression specs, 8.8 sounds a bit low.
