i have never seen a iron rec port intake.. all gm i seen were alum .i not saying they never did but if so its very rare.... you could do some work to a iron O port but why??? if you need it to be iron for a class just send out a alum intake and get it metal sprayed with steel

Pat thanks for the reply, tell me more about this metal spraying like how its done and price, allso who provides the service is it something i have to send off or something thats done localy? thanks
