Thicker head gaskets/ less compression...

Hello all, first time in the racers forum here.
I'm looking to use a thicker head gasket to lower the compression in the 440/493. Currently I am at 10.7 and am having some detonation. I have chosen a bigger cam with a later intake closing and the thicker head gasket figures into this as well.
The engine currently has a quench distance of .056, so there isn't much quench happening anyway.
I'm interested in going from the .039 gaskets to a common .051 size. I've seen them listed with different bore sizes. I have seen 4.410 and 4.590. The 4.410 will drop the compression to 10.45 and the 4.590 will take it to 10.36. My question is.... Is there a problem with using the bigger bore gasket on a standard block? At .180 wider, I couldn't imagine that it would be at greater risk of blowing out. I have no intention of running nitrous or any other power adder.
Thanks, Greg
