hey guys had a look and search on web just wondering if anyone could explain it a little easier including with my valve lift which is 115. And how to adjust vernier etc, read you need a dti gauge? Defo need this? If so anyone got one I could borrow over weekend in edinburgh area? Read a few diff posts some say this way some say divide by 2 etc so got my self pretty confused over it all, so hopefully someone can give me a run threw the full thing head is also off car so be able to time in bottom end better as I can see piston and bore? Cant take to a tuner as mot up so trying to get it done for mot then take it for full setup including cam if I aint got it spot on. Cheers for any help in advance.
