i want to put new heads on my evo 9 will it matter if i have a stock yurbo or should i wait till put a new turbo in

 

There is only one head on the Evos. There is only one header on an Evo or AKA manifold... based on your post I say you mean header (manifold) you can get a maniflold but I doubt it will do much for you id recommend waiting for a better turbo or upgrade your stock IX turbo to a 20G-9 and get a tubular manifold

 

did you mean to say cylinder heads? or exhaust manifold HEADers?
