3900 Header Flanges

Product Information

These flanges have an angled bolt pattern vs the 3.1/3100/3400/3500 heads that are straight up and down.  The 3500 based off the 3900 with less stroke will have the same heads as a 3900 so if you are planning to make headers, these are a great start.  That is, the 3500 with VVT, like the 3900 has is identical. Priced as a set (2).
