01 blue ss

I'm getting a 406 sbc refreshed and I'm trying to see what headgasket to go with. It had cometics on it before so I want to go back with them. What I have a question with is the bore size. My bore is 4.155 and cometic sells a 4.165 gasket and a 4.200 gasket. Will the 4.165 bore be too close or will it be ok? Or do I just go with the 4.200 gasket?
