Speedway Motors 9300100H Details

These compact, tight-fit headers are designed for Small Block Chevy (S/B Chevy) engines with round port heads, making them ideal for applications where space is limited. Featuring 1-1/2" primaries and a 2-1/2" collector, these block hugger headers simplify even the most challenging installations.

Armor Hot Coating (AHC) is a heat-resistant ceramic coating applied to the exterior of the header. It reflects heat back into the header tubes, helping to retain exhaust heat and improve exhaust flow. This can lead to increased horsepower, while also keeping the headers rust-free, cleaner-looking, and more durable with proper care.

This coating can withstand exhaust temperatures of up to 1300°F.

Designed for round port S/B Chevy cylinder heads
Driver side collector is approximately 2" from the pan rail
Passenger side collector is approximately 1/2" from the pan rail
Flange thickness: approximately 0.212"
Includes reducers, gaskets, and bolts
Will NOT fit angle plug heads
Will NOT clear 'clam shell' style motor mounts (common on 1973-up Chevy applications)

NOTE: Most tight-fit applications require shorty spark plugs for proper clearance like those offered by Accel.

Overall Assessment

Our product provides a perfect fit for engines in various car models, even those with tight space allocation. Commended for its good quality and great looks, it outshines competitors with its practicality and clear steering linkage. The ceramic coated huggers are perfect for specific motors and render the product as beautiful and period-correct. Ease of installation and good spark plug clearance add to its features. However, customers suggest caution with the fit of supplied bolts. Lastly, the product was ideal for many projects, providing an excellent balancing act between quality and price.

Model A project, Good quality for the price

I purchased these for my model A ford project. I am using the speedway model A chassis with a small block 350. I needed the clearance for the steering shaft where other headers or manifolds were in the way. Good spark plug clearance. I provided photos.

I haven't installed them yet but they look nice. The only thing that would be better is if the pipes were flush with the mounting flange other than that they should work just fine.

They fit well and look good, no leaks even with supplied gaskets (usually prefer different kind but I took a chance). I liked that the supplied bolts had a small head for easier install in a tight area, but the size was a little off, just a little small, so I was worried that I would strip them if I ever had to reef on them. Used anti-sieze and tightened to 15 lbs.

I would buy again
