Exhaust Adapters and Header Flanges

Originally designed by Neil & Parks for the 14° Pro Action Small Block Chevy Head, these 6061 Aluminum Exhaust Adapters will also fit 15° and 18° SBC Heads. We also make models for Hooker and Stahl Pattern 23° SBC Heads, Early Model Hemi with stock type exhaust port or round port, DRCE style engines, and 2.5" Center to Center Small Block Fords. We can make any design adapter or flange with either a print, or a "rubbing" of the port and bolt outlines. All adapters have a notch to clear the valve cover and bolts are positioned to clear spark plugs.

Our Header flanges are made from 1018 Cold Rolled Steel, also available in Stainless or TI.

Set of Adapters $150, Set of Flanges $125
