Dave and All, I'm in the process of trying and I mean trying to get the head off my '31 STD 8 Packard. I'm doing this so I can replace the valve springs due to some of them being broken. I know my gasket is trash because of trying to pry under the head to get it loose. It seams to be rust to some of the head bolts. I have sprayed them with some PB blaster I will see tomorrow if they brake loose. Any suggestion would be much appreciate. Thanks, Tom
