That I dont know....new combo and when I bolted up my Headman's to the bare head I noticed there was a definite port alignment problem. They look ok and like I said for 300 bucks they are worth a try. I have used these headers for years on my street car and they have definitly improved over the years in quality. I know there are alot of people out there who swear by 3000 dollar stainless headers but im a normal working man who can justify that.
