I'm about to do a head gasket on my Mk3 Astra, and while I've got it apart I was wondering if anyone has any old performance parts kicking around the garage from the old days of Nova racing?

Fast cams, solid lifters, etc?

Also a second hand LSD would be great.

I'm not looking to spend loads, but not freebie hunting.

The closer to Stansted Airport area the better.
