Header Spec’s:

This header is available in 2” or 2 1/8” tube sizes with a 3 ½” collector, also in a 2 ¼” tube size with a 4” collector. All of our headers are hand made so we can build them for any engine deck height and any cylinder head. In any tube size you need.

What Fit’s

It has excellent ground clearance and spark plug access. It is designed for aftermarket oil pans with side sump kick outs, the available room from the side of a stock oil pan is 4 ½” on the drivers side and 3 ¼” on the passengers side. On our design car we used a Milodon low profile oil pan #30951 or #30956 and the bottom of the header was even with the bottom of the oil pan. These oil pans allow easy access to the oil filter. This header requires a mini starter. Steeroid rear rack fits.

This design fits side motor mounts or motor plates, clutch linkage and up to a 9” power brake booster. When installing your steering column the upper “U” joint needs to be approximately 5” to 5 ½” from the firewall or in the same location as the factory steering column rag joint, which will allow the column to easily clear the header. If your car has a Lakewood style scatter shield you may have to slightly trim the outer edge of it under the starter area for clearance.

This header will not fit a factory air conditioning box on the firewall, a full size GM factory starter or column shifter linkage. It requires that the engine be in the correct position. The engine should be setting on small block front motor mounts, 327 or 350 only. (See drawing that shows measurements) If you are using a poly engine mount it would be a Prothane #7-504. If you are using a solid engine mount it would be a Moroso #62530. It requires a mini starter. It is limited to a 9” power brake booster. Fits many aftermarket oil pans with kick out sumps, see info above for available room.

Installing the Headers: Pro-Tour Style

To install the passenger side, depending on the size of the oil pan kick out you may or may not have to remove the starter, remove the spark plugs and install header from the bottom.

To install the driver side remove the spark plugs, clutch linkage, oil filter and the center section of the steering column. You may have to raise the engine about 1” and install the header from the bottom.

Installing the Headers: Race Style

The race style headers are all single tubes and slip on collectors.

On the driver side install #1, #3, #7 tubes from the bottom and #5 tube from the top.

Then install the slip on collector. The collector only goes on one way, so be sure to read the installation tips page regarding slip on collectors.

On the passenger side install each tube from front to back #2, #4, #6, #8,  from the bottom, then install the collector.

It’s important that you refer tour Yellow (Header Installation Tips) page for additional information. It will make the installation go easier and save you time.
