I just recieved the F22B DOHC head that I purchased from PRIMOCB7 (awesome seller and a great guy). We checked the fitting of the F22B head to the F22AX block via the headgasket, and YES!! It fits perfectly, without any modifications. All of the drains, ports, etc. line up flawlessly. So all you guys who where wondering if the F22B DOHC head would fit onto the F22AX series blocks, YES IT WILL WORK!!
NOTE: This picture was taken before cleaning and dissassembly, so its dirty as hell. Here's the photo of the F22AX head gasket on the F22B DOHC head. Enjoy:
