Hi, Am just doing some work on my GT4, have had to take off one of the inlet manifolds (what a pain to remove!) I think, my car must have had a top end rebuild at sometime, but was wondering what the original material for the valves would have been, the current inlet valves are non magnetic, so I assume stainless. Am hoping, if the inlets have been changes, so did the exhaust valves..... Anybody know if the original inlet valves were stainless? Thanks Nigel
