The CS11 is a small block Chevy conversion header for V8 engine swaps in two wheel drive (2WD) Chevrolet S-10 truck and Blazer (incluidng GMC S-15) applications. The CS11 is a very compact header design that fits cleanly between the engine and frame rail. This is NOT a fenderwell exit header! The CS11 header works with virtually all engine swap kits. If using the Speed Center mount kit you may prefer the #CS10 header set, and for LS1 engine swaps, please use the #CSLS1 header set.

The use of solid motor mounts, engine plates, or the installation of a torque limiter is strongly recommended to prevent the engine from shifting would may cause the steering to bind.

Copper Collector Gaskets are recommended for all Sanderson headers. Sanderson Headers do not include collector bolts due to our customers' wide range of preference.
