The Spitfire I had planned on campaigning in HS this year decided to blow a
head gasket, so the rebuild I had planned on doing later this year to move
into Street Prepared has been moved up a bit. A couple of questions that I
couldn't find answers for in the rules -
1. is gasket material unrestricted? ie, can I use a metal head gasket
that's the same thickness as the stock one?
2. Are valve grinds restricted? is a 3 way/5 way/radial grind ok?
3. Are valve springs restricted to stock?
thanks!
