Afternoon,I should firstly apologise as I've not been on here for !Removed! ages, think it's called being a grown up? Boring!. Anyway,just about to convert my legacy gtb to single turbo and I've got a pair of heads in my garage which my mate tells me has RA CAMS.i have STI CAMS in mine as it is but I have them and wondered how do I check if they are and is it worth changing them over or not?apologes again,gambit will undoubtably give me a seeing to whilst blindfolded in a field again....
