I really do hate hindsight Mark, I'll be in touch about the headers
ya know, I 'had' a pair of genuine cast iron headers for a grey, I had the canadian cast block with the big GMH logo embossed on the side bored to suit Bedford truck pistons, had the balanced crank, triple strommies, big cam, hot head and lightened flywheel..I sold it all as a lot years ago when I decided to go the XU1 styled 202 with an iron case 5 speed...bloody idiot!
I have however managed to keep many other parts for the sideplates thankfully but the 1 part I really need to get things rolling is a useable crashbox from anything pre '63 EJ at a realistic price. It doesn't have to be good good, just useable
