Speed Engineering LS swap shorty headers are made out of 304 stainless steel and offer great quality, performance, and affordability. Our LS swap shorty headers are mandrel bent, tig welded, and feature natural stainless steel construction. All of our LS swap shorty headers have been dyno proven. We stand behind our LS swap shorty headers in saying you will not find a better fitting, quality built, budget header for your vehicle.
"Our LS swap shorty headers also have improved features over competitors. We utilize V-Band collector construction, merge spikes, port matched flanges, and improved header to block/chassis clearance".
Features include:
Note: "For LS series engine swaps only" These do not work on standard SBC or BBC.
Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance. Our headers are tucked in tight due to narrow older frame clearance.

They are amazing the best and good price. I'll not use anything else from now on
Bought these with the standard bolts for my 1979 cutlass supreme gbody with a 5.3 ls th400 swap fit perfectly obviously had to cut off the transmission tabs but the website doesnt say they fit gbody they absolutely DO!
Great fit and finish. Most importantly, these dudes rock when it comes to customer service! Can’t beat the price for these quality headers.
I Ls swapped a 90 f150. Was having a hard time finding headers to fit. This set was the key. So y’all can add ford truck to description as well! Great product
