I've used the Holley blue gaskets and reused them many times with jet changes.
I did have an issue a while back where the initial installation was fine but subsequent re-used caused a leak, apparently after the gasket was initially compressed. Something in, on or around the carb was keeping the bowl from fully seating but the new gasket was thick enough initially to keep it from leaking. I just don't remember what it was!
Is your problem only with one bowl or both? Mine was rear only.
Not to use it as a permanent "fix" but to see what happens.....try 2 gaskets
