New for the DIY guys, grab the DXF and have your parts cut locally. No waiting, no shipping, no markup. This file is designed for the Pontiac Speedmaster V8 engine headers flange. We recommend running 3/8″ to 1/2″ material, so you’ve got enough thickness left after welding and final surfacing. Once purchased, you’ll get an instant download link to the DXF file. Please note: Designed around Speedmaster Pontiac V8 cylinder heads. Compatibility with other factory or aftermarket heads is likely but not guaranteed. Buyer is responsible for verifying port shape and dimensions for their specific application.
