Stainless Header Flange to Fit Noonan LS EDGE Billet Heads

Precision laser cut from 3/8" thick 304 Stainless Steel, our header flanges are manufactured in the U.S. and are machine surfaced. These header flanges are specifically made for the Noonan LS EDGE Billet Heads. These have a unique bolt pattern that does NOT fit other Noonan or other manufacturer's cylinder heads

We have these available in 2" and 2 1/8" port sizes. 2 1/8" is the maximum port size to still utilize Noonan's O-rings for the exhaust ports.

We carry over 450 different header flange designs, so if you don't see the flange you're looking for, talk with one our tech reps about custom header flange cutting.
