Clifford Performance -- a header for your L or F Head

We had a discussion a while back about ways to improve the performance of your L or F Head. Clifford Performance specializes in improving the performance of in-line engines -- even their slogan 6=8 signifies that you can get the horsepower of a V8 out of inline 6s with some modifications.

If you have an inline 6 cylinder or 4 cylinder engine this site is worth checking out. Here's an example of the F or L-head header.

Gregory, Here is a link to their 4 cyl Jeep header... https://cliffordperformance.net/store/ols/categories/4-cyl It is still made. They also make headers for later Jeep engines. https://cliffordperformance.net/store/ols/categories/jeep-25840 And their phone number had changed.
