Although a proper compression test should be performed on a hot engine, WOT and the fuel disabled, I don't think it's gonna make much difference on those low cylinders.
A good cylinder leak down test on all cylinders will tell you where the leak is most prominent and help you make a better decision when you pull the heads and get a chance to visually inspect the cylinders.
