These ARH headers do look great, and the price does make you take a deep breath! However, since I'm running W2 heads on my engine it appears I can't use these, unless there's an adapter plate that will work with them.
currently, they only offer standard head headers. In 2 sizes.
1 3/4, and 1 3/4 to 1 7/8 step…which is what I bought.
I got a 10% discount being ex military, and I am selling my current headers, so all that helps a little bit. But still are pricy, no doubt.
