I have for sale a big valve non vvc head which has been polished and ported. The head was running on a rally car and has been cleaned, had now valve guides fitted and a skim. Was only removed by previous owner to fit big valve vvc head. This one has 31.5mm inlet valves and 27.3mm exhaust valves. Porting looks nice although I havent been able trace back who did the port work. I have included a set of 285h cams with spigot for dizzy cap, piper vernier cam pulleys, a new set of max speeding forged rods and a low milage set of omega forged pistons which were checked…
