"cylinder head removal kit"

[Dave Mann]

Thanks all. I'll investigate Colin and Andy's designs further (it just seems a good idea because of the tuneable amounts of considerable force) Ironically, the point about the aluminium heads threads might be why it hasn't established better use? Pointless making something if it can't be used in all circs.

And yes, will do the start up thing first!

You mean like this, always worked for me
