The compact, low profile design of Hedman's Block Hugger Headers is ideal for factory manifold replacement, or engine swap projects that do not have a header designed specifically for the applications.

All Hedman street Hedders are MADE IN THE USA, and are backed by a lifetime warranty against manufacturing defects! HTC coated stainless models also available.

If your engine does not have factory cylinder heads, we strongly recommend you contact the aftermarket head manufacturer to confirm that the deck angle, exhaust port height and spark plug angle/position match the factory cylinder head design, before ordering your headers. If you are still unsure, please contact the Hedman Tech lines M-F 8am-4:30PM (Pacific) @ (562) 921-0404.

IMPORTANT!: Installing coated headers on an engine during the break-in period will cause discoloration. We recommend the use of factory manifolds, or an old set of headers, during the engine break-in period.
