Following some repair work carried out on the cylinder head of my r56 cooper n12 engine want to fully strip the head in order to clean it up properly.

The inlet camshaft is still in place (exhauat remove due to damaged valve and seat), are special tools required to remove this? Or is it just a case of unbolting it.

Can anyone also recommend a valve spring compressor which will work on the n12 head given the valves are somewhat recessed.
