How much decking is to much?

we cut an early 360 block back in the day .090" with no problems for a guy that had forged pistons with a 1.591" comp. height. a good machine shop does not just square a block, the equalize both sides. so with good rods and pistons we do not need different head gaskets. I would forget cometics overpriced 2 different gaskets and run 1008 fel pros and cut 1 head .005 more. I think the blueprint on a 273 318 340 360 is 9.600" and a magnum 318 360 is 9.560"
