ahight i bought a set and the air check valves dont fit, im sure the tubes on the header is 5/8 and the one on the check valve is 1/2. i have a 96, is there a adapter i can buy? did i they give me the wrong year?

 

Are these the magical 60+ RWHP pacesetter headers we have been reading about?

Anyway you might want to consider just stripping out the AIR system and plug the headers with fittings from any parts house.

 

They should fit, I remember mine fought me for awhile and it took me about 15 minutes before I finally caught a thread and could get it tightened down.
