RichandHazel, I wish I'd read your reply earlier about Stuart at the Leeds branch of Euro Car Parts...
...I went to my local branch today and bought a set of lifters for £122.00 and a set of head bolts for £20.00, both inc vat. The timing chain will be there tomorrow and thats only costing me a tenner.
I also called GSF and they matched Euro price for price but seeing and Euro were closer to work, I went there.
