If I send the heads away to be skimmed I assume I have to send it bare, valves etc removed.

As long as I keep track of which valve went in which position is it as simple as just putting them back in when I get the heads back or do I need lap them or do anything else with them?

No, leave the valves in..
It’s up to you if you want to relap the valves and put new seals, but no need to remove to have them skimmed

If you hadn't moved house and you told him you were bringing them in, Lyndale Engines in Peterborough will skim heads while you wait. It's actually fascinating to watch the machine removing metal from just a couple of spots and then a bit more each pass.

I bought some ARP studs from Real Steel around a month ago for £140.33 including the lube, so slightly cheaper than Rimmers.

Turns out that's where Rimmer Bros get theirs from too! Had a look at the Real Steel website but went with Rimmers as it was easier to order from them (I'm too lazy to be calling people up to do stuff and I like having an online order that I can view for tracking purposes).

The box arrived with Real Steel stickers and part numbers on.

Is there anything special I need to to regarding the LPG kit fitted to the intake manifold? Can I just unscrew/unbolt it as necessary or do I need to do anything cut off the LPG supply and stop it all leaking out?

Provided either your front or rear solenoid work as they should it won't leak out as they shut the supply off (they should both work of course!), you will just get a small amount of leakage from whatever is in the pipework to the injectors from the vapouriser. If your concerned about that then disconnect the feed from the coil to either solenoid and let it run till it switches back, or if its a single point tank turn the tap on the valve off and run till it runs out.

Done somewhere ventilated its not a worry really as its a small amount you will be losing.

Excellent, cheers :)

Solenoids should be fine. No issues with the system running and it's only a few months old.
