no he had a blue top with gixxer itb's. if your talking about a new motor then cool! i dont care too much for 20v head because 5 valves in one combustion chamber does not make it easy for bigger valves. itb's is a fav of mine though. marks the man with the plan, and large amounts of toyota know how. so ill trust what hes doing will be the end all be all of 4ag. or maybe 3sge?
