Help one of my springs has broken on no 1 cylinder does anyone done or know how to change spring without taking head off paul
 
No.
A valve spring compressor is going to require the head to be removed.
Even if you bodge something up (which will take as long as removing the head) then you run the risk of the valve dropping into the combustion chamber unless you have no. 1 at TDC.

On the plus side it'll give you a chance to check everything over - on the downside, you need to be careful the head gasket re-seals properly since it has already been compressed (a bit of sealant should do the job), and this is something that is more enjoyable when it is light and warm (rather than dark and cold - metal in winter feels extra cold and you seem to cut yourself more easily when you can't feel anything).
 
It can be done. I don't know how because it didn't have to be, but there was a bit of inner valve spring on my sump plug magnet once. Everything was stripped back only to find it was from an old failure and had already been replaced. The head was NOT coming off even if it needed to be replaced, at least as far as I understood.
 
I have seen mention on rennlist of using compressed air to hold the valve in place whilst the spring is changed, probably worth having the head off though, to check the valve guides etc. and inspect the other springs,

I presume the head gaskets are eyeleted?

If so you must use a new one.

I have a 30 year old Norton, solid copper gasket that you anneal (heat to cherry red) then reuse. though it always ends up weeping oil.

Just out of interest....

What is the price of a 944 head gasket?

Are the turbo gaskets the same?

Do the valve seals come with the kit and would these be worth doing anyway it you had the head off?

.......so many questions...........
