STEPPED HEADERS
Most ACP Headers are built in a stepped configuration (Multiple tube sizes in the same primary tube). Stepped headers usually increase either midrange or top end power, depending on the base header tube size relativity to its power level. A stepped tube also helps to tame reversion, gases do not like to go from larger diameters to smaller diameters. Stepped headers will work better with some engine combinations than others but usually perform better than a straight size tube.
TUBE SIZE
The tube size requirement for an engine is a function of the HP the cylinder is putting out, how good the exhaust port is, intake manifold pressure, and the most critical part of the RPM range. We will be happy to assist you in choosing the correct size for your engine at the time of your order.
AFTERMARKET CYLINDER HEADS
One of the things that set us apart from the "Mass market" header companies is our ability to build almost all of our V8 headers for aftermarket cylinder heads. Many heads (AFR, Brodix, Dart etc.) have raised exhaust ports and a wider casting. Building a header for a conventional SB Chevy head then bolting that same header to a cylinder head that is taller and wider can result in spark plug issues and frame clearance problems. We have developed adjustable jigs that allow us to adapt each design to virtually any cylinder head. We can build most of our headers to fit spread port heads and 18-degree heads also. We build all of our headers to YOUR cylinder heads.
FLANGES AND ADAPTERS
Some SB Chevy header designs offer a choice of standard or adapter flanges. Most SB Chevy headers are available with the Stahl adapter flange in 1-3/4" and larger. But adapters are required on SB Chevy's (Or any six bolt SB Chevy style head) using 1-7/8" and larger primaries. We have flanges for most cylinder heads such as Brodix, Dart, AFR, 14 & 18 degree, Mopar, Ford and Imports. If you don't see it listed in our Flanges section, give us a call.
COLLECTORS & ADJUSTABLE PRIMARY PIECES
Removable collectors are available on all models in 2-1/4" thru 4" outlets in 1/4" increments. Combine removable collectors with adjustable primary pieces to fine tune your headers for max performance.
PAINT AND COATINGS
All fully assembled headers are available painted with the traditional Stahl silver 1800-degree heat paint.
We do not do any in-house ceramic coating. If you choose to have your new headers coated, we can ship them to you bare, sprayed with a rust inhibitor. All bare headers must be fit checked on the car before sending them for coating! This is the time when we can address any fit issues. Once they are coated, we cannot make any modifications or changes!

If you do not see what you want, call us. We may have it or can make it. We are the #1 quality and performance header manufacturer who makes only race quality headers. Racers are the core of our business. If you have any problems, let us know.
SERIAL NUMBERS
All fully and partially assembled headers are serial number stamped during production. ACP Headers has the Stahl serial numbers and build info for each header going back to 1981.
