I have 2 sets of Nissan 300zx heads. One set of heads has been ported on the intake and exhaust side no cams included on these. The 2nd set is stock and is 100% all the cams and valves are there. I also have a gasket matched lower intake as well that I am taking offers on. I would like 450.00 or obo for both sets of heads. I have a ton of twin turbo parts I am looking to get rid of. Please ask any question you have. Thanks
