Steel header flange for custom fabrication of exhaust header on 20R, 22R, or 22RE engines. 1/2" thick flange with 1-1/2" or 1 5/8" ports. This header flange is the same one we use when constructing our headers in house. It will have a groove cut out on the cylinder head side to provide better welding and penetration of the weld when you construct yours. If you have any questions about this product please call us.
NOTE: The "Race" Style flange utilizing the 1 5/8" primaries will not have Air Injection mounting locations (not smog approved).
