NOS GM Stage 1 one heads I have a pair of NOS GM Stage 1 heads i came across i would like to sell.they are 73 casting number heads(1241860),but they do not have the 73 cast on the top of the exhaust port like the production head does.The date codes are e10,and d30.these are nice clean,no rust bare heads ready to use.Why spend alot of money on fixing up a set of used heads when you can have a brand new set.Im asking $950. for the pair less shipping.might be able to work out some sort of delivery in the midwest( Indy,st louis,chicago, Davenport.can also set them up ready to use ,with stainless valves,spings etc. for additional cost. serious inquires pm your email for pics or call 815 844 7852 email lynsmithnova@frontier.com thanks Lyn
