‘59-’64 Cadillac with 472 / 500 / 425 swap.

Premium mid length header. Fits ’59-’64 with 472 / 500 / 425 RWD swaps with little or no mods, may also fit some ’54-’58 swaps. CNC Mandrel bent, 3/8 flanges, 3″ collector. 1 3/4″ primaries.

Note that these use a clamp-on collector (included), rather than the traditional 3-bolt collector, due to space limitations.

For ceramic coated headers, please add EX61101 Premium Ceramic Header Coating (Silver) to your order.

Easy fit, properly designed for Cad applications.
The following information applies to all headers unless otherwise noted.
Made in the USA. Fully CNC mandrel bent heavy gauge tubing, jig welded, with 3/8 flanges, machined flat after welding, for a reliable seal.
Headers are a mid-length design, 1 3/4″ primaries and 3″ collectors, designed for optimum performance from stock to performance builds. Higher end builds (over 500 real HP) may benefit from larger tube headers. On most stock and street performance builds, these headers beat anything else available on the dyno.
Prices are for headers in bare steel, unless otherwise noted.
Note: Headers are designed to fit listed applications with no further modification, assuming the engine is mounted in the location we mount them. Different installations may require custom fitting.
