No worries, mate, no worries!
Got the casings bolts (stainless ones from Inox Fasteners in Southampton - quality kit), need to look at the ones on the head itself. Want to replace all the visible ones and also the head studs too 'cos they're looking a bit manky as well.
If you could post up the info on them, that'd be a great help, y'know?

I'm too unimaginative to think of anything witty ...
