Have searched the forum but can't find what I've seen before.....
Simply put - What clearances do all you Zedheads suggest please as the Saxon needs doing now it's got a few miles on.
Depends on if ur running std. cams or not. Im running old race spec Kent cams which have a much larger gap specified on theyre data sheets and website. I imagine ur running the std. cams tho with a turbo setup. I always err towards the larger value so I dont have to do em so often.
