560SL M117 Head Removal - Which Bolts

[My-red560SL]

Before I ask my question I want to let you know I am a novice. I have never removed or rebuilt an engine, but here I am. I know this is a stupid question for those that know, but I don’t know which bolts I am supposed to remove from the heads to remove them. The manual I’m using is so confusing I’ve given up trying to follow it.

The diagram in the manual shows 18 hex bolts, but I find more than that in total. Which bolts am I supposed to remove? One pic shows removing a bolt on the cam. Am I removing the cam? Can I remove the cam? If so there are 10 of those bolts on the cam alone. I simply can not follow this manual. The tightening order only confuses me more.

I have the engine out, timing chain & cam gears off and I’m ready to remove the upper slide rails (step 16 of this horrible manual). Eventually I do need to remove the cams and bring everything to the machine shop. This same manual says I need a valve spring compressor tool to remove the cam. Is this true? I can’t find the tool that’s listed in the manual for sale anywhere.

I’m not a mechanic. It all started as a rear seal replacement and before I knew it the engine was out and I’m taking it all apart. It’s my rabbit hole.

Any help would be appreciated.
