So I have to remove the cylinder head from engine block?

22

Or just the cam cover?

My mistake, its 1 3/4.

The plugs are behind the intake manifold as he said. They don’t seem to go bad, unlike those in the block, unless I’m mistaken.
Can’t hurt because they will be accessible, so better do those as well.
The one at the rear will be the problem :grimacing:

You will have to remove the engine to replace the one at the back just below the cyl. head and above the gearbox.
All others are accessible without removing the engine but you will have to remove the exhaust manifolds, the carburetors and inlet manifold.

Thanks for your patience…:grinning:…then I’ll tell you how it went …
