Speed Engineering 25-1156 natural 304 stainless-steel 1 7/8-inch longtube headers for Gen V LT1/LT4 swaps. Speed Engineering reuses this exact SKU for 1967-1969 Camaro, 1968-1974 Nova, and 1965-1970 GM B-body applications including Bel Air, Biscayne, Caprice and Impala. B-body installations require adjustable mounts with approximately one inch of rearward offset.

Includes graphite gaskets and installation hardware. Upgrade to vehicle-correct SMG LT MLS gaskets and/or add SMG 9070C Ceramic Plug Wires. Their ceramic boots resist header heat and melting, and they are the only plug wires used on SMG in-house header builds.

Processing & Shipping Overview

Processing occurs before shipping.

Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.

Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.

For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
