Loosening and retightening a head with some run time

[Silverspy]

Sorry for the newb question but i havent seen this answered of asked anywhere after a good search. The motor has 500 miles of break in, arps, cometic. Would it be ok to loosen in sequence one at a time and re tightening so as to not compromise the seal of the head gasket? Would that be effective? Or would it be better to loosen them all and then re tightening them. A simple yes no to whatever will do, thanks.

I am assuming that you are doing it to check to make sure they are torqued correctly still. I would do it the individual way, one at a time. Like you said that way you dont compromise the integrity of the seal.
