Back when I worked for a Volvo shop/yard, it was not at all uncommon to see B230F engines showing 175-200 psi compression numbers after being run for a few minutes at varying rpm. B23F engines frequently would show 225-230 psi straight across.

I would've had the machine shop skim the head while it was off, though. Even though you reinstalled the same head onto the same block, there may've been some slight warpage, which may be causing the head gasket not to seal properly.
