A good friend of mine who I thoroughly recommend for engine setup and rolling road work.
He runs a small friendly firm specialising in cylinder head modification for all four stroke engines and has been trading since 1985.
He also builds engines for MGBs, MGAs, Midgets( A Series and 1500s ), Rover V8s and MGCs.
One of the busiest websites for classic car listings. Much more than MG, nearly every model is covered - old and new. I often use this site to advertise and there's plenty on there to keep you occupied!
