Last time I claimed I had them fingered in every corner, pictures the lot only to have them send a sorry letter and a few stamps lol but fook me how can a gearbox be lost..must be like a narnia post depo where does it all go!
I remember me seeing something of a 8.5mm lift over stocks. I think they were put in 5E they ran. I believe stock 5EFHE cams are a slightly higher lift over stock 4E's..8.1mm, not 100% certain. Rob sr might know more bits of info
