Header Specs:

This header is designed for any tube size up to 2 ½” with any collector size up to 5” or our collector mufflers up to a 6” size. It will fit Alston’s side motor mounts or motor plates. The engine must stay in the correct position. This design has 2 tubes on each side that go around the frame. This allowed us to get the best possible ground clearance, oil pan room and spark plug access. Any mini starter will fit a full size GM starter will not fit. With skinny drag type front tires they will clear the header tubes, with big tires on offset wheels they will rub the tubes. The oil filter is accessible even with a typical 7 quart oil pan with bottom sump kick outs. Measuring from the side of a stock oil pan we have 2 ¾” on the passenger side and 4” of room on the driver side for large oil pans.
The steering column must be installed per Alston’s instructions. This header will fit a power brake booster, but is not intended for air conditioning, column shifter linkage or clutch linkage. If you are using Alston’s inner fender panels they will have to be trimmed to clear the tubes around the frame. Install the headers first then trim the panels to fit.

Header Installation:

This header is designed with individual tubes and slip on collectors. Install the tubes on both sides starting from front to back. The 2 back tubes on each side are the ones that go around the frame. Only snug the header bolts until the collectors are installed then go back and tighten all the bolts. Refer to our header installation tip’s page for additional instructions.
