HEADER INSTALLATION INSTRUCTIONS

Part #D325

1970-72 Camaro, 1968-74 Chevelle/El Camino

396-502 Big Block (Std. Deck Only)

NOTE: 68-74 Chevelle/El Camino MUST have correct Motor Mounts and Stands (frame brackets) for 350

or Big Block, L6/307 motor mounts and stands will NOT work.

NOTE: 70-72 Camaro MUST have Big Block Motor Mounts and Stands (frame brackets). Small block and

universal aftermarket will NOT work.

NOTE: 1973-74 Chevelle/El Camino have a narrower frame than the earlier years. Due to the

large 2” diameter of this header, it will be necessary to modify the #1 cylinder tube on the right

side by denting it slightly for clearance. If you are not comfortable doing this, we suggest you

install Doug’s Headers part #D313 with 1 ¾” tubes instead.

NOTE: Will NOT fit with 825 Saginaw Power Steering box (will work with 625 box)

PerTronix

thanks you for choosing

DOUG’S HEADERS

, the best fitting, highest quality header on the market. In

order to realize the full potential of our good fit, please read and understand these instructions completely prior to starting

work.

Check to make sure you received the proper parts for your application. The header number will be stamped on the

engine flange. If you are unsure you have received the proper parts call before you start work.

Be sure to work safe! Whenever you work under the vehicle be sure that it is located on level, solid ground and is

supported by adequate safety stands! Remember: Hot asphalt will not support most jack stands!

Many factors affect the installation of headers, some of which are broken or aftermarket motor mounts, accidents that

impact the configuration of the frame, and/or the installation of different engines or aftermarket cylinder heads. Most

installations require some welding. If you are uncomfortable with welding operations, we recommend that you contact a

professional exhaust system specialist to install your new headers.

Attention Customers breaking in new engines: Due to the extreme heat generated during the break-in process, the

appearance of the ceramic coating may be altered in certain areas. The protection characteristics and thermal barrier

properties of the coating is never compromised. It is recommended that a cast iron manifold or old set of headers be used

for this process.

Notice: The coating of these headers can be marred or scratched during installation. If the header needs to be returned

and is damaged, you will be charged for recoat.

DISASSEMBLY
