Fits aftermarket-pattern Oldsmobile cylinder heads. Not compatible with OEM Oldsmobile exhaust ports. Priced as a complete set!

Cut from certified 304 stainless and machined complete in-house. The face is 1/2" thick to the stub projection, and a .125"-deep counterbore drops your tubing in square and holds it there while you tack.

SPECIFICATIONS Material — 304 stainless, mill certified Thickness — .500" flange face to stub projection Counterbore — .125" deep, machined to selected primary size Configuration — One-piece

FITMENT Fits: Aftermarket-pattern Batten and Edelbrock Oldsmobile cylinder heads Does not fit: OEM Oldsmobile cylinder heads — the port location and bolt spacing are different

CUSTOM PORT MATCHING Custom port matched flanges are made to order. Matching requires additional steps to guarantee the flange lines up with your specific head, so fill out a Contact Us inquiry before purchasing rather than adding to cart — we'll confirm your port dimensions and quote the work.
