Head Gaskets

[303Foxfire]

Hi fellow VXers,

I am currently TRYING to replace my head gaskets, yet I have removed every bolt and hose attached to the RH cylinder head (following the manual to the T) and I can't get it off. I thought that it was necessary to unscrew the exhaust manifold head from the cylinder head via the four bolts visible from top view. Are there more underneath or am I missing something? Please help, thank you!

Shop manual says 8 bolts for the exhaust manifold...but no diagram of exactly where they are.
