Hi zone.
In the process of replacing the head gasket on my M40. I've removed the intake, cam sprocket and head bolts but I can't seem to remove the head. I haven't tried forcing it but I'm reluctant to since the wiki says it should just lift off. Apologies if it's a stupid question, but do the spark plugs or exhaust manifold somehow connect to the block? I don't see how they would but those are the only things that haven't been removed.
Appreciate any help.
