So ScottieMV6....what did you use and how did you get on?

Not used anything yet. Been removing all the crap etc off the faces using scotchpad etc.

Don't think I am going to use the dishwasher though TBH. Think I will soak them in degreaser and then powerwash

Gonna do all that on Monday though as its my birthday tomorrow so having a night away tonight

Degreased and powerwashed the heads yesterday and they are now a lot cleaner than they were.

Might sound like a daft question but do they have to be bone dry before re-assembly?

I would blow an airline or similar through the oil galleries to dry them and blast out any crud that might have been washed into them. Apart from that a little dampness won't do any harm.

Make sure the threaded holes are clear.....you dont want a bolt/stud to hydraulic on insertion.

[ScottieMV6]

Ok thanks.

Is there anything in particular I should know when re-assembling?

Mark - James mentioned you had done a follower servicing guide but I can't find it. Can you let me know how to go about it?

[Marks DTM Calib]

Where your followers noisey?

[ScottieMV6]

Not that I know of!

[ScottieMV6]

Where your followers noisey?

I assume then if they were not noisy they don't need servicing?

Yep

[ScottieMV6]

Thank you....off to start re-assembly now!

[ScottieMV6]

One head completely re-assembled, other one just needs exhaust manifold etc. re-attaching.

Have to say that 20NM on the exhaust manifold nuts seems a bit light but I am doing everything by the book!

Is putting the heads back on the car a 2 man job or can I do it myself? 

[Marks DTM Calib]

I have done it myself a fair few times!

I also do the manifold nuts to 25Nm.....ensuring the studs are in the head before the nuts are fitted.

[ScottieMV6]

Ok - I'll nip them up another 5 NM tomorrow just to be sure. I did put the studs in the head first

Yep

I would at least squeeze the oil out first.

If the valves have been reseated then the followers need to be compressed otherwise they will remember the previous learned valve clearances (which won't match the reseated valves) and might result in no compression.
