BBC bare rectangular port heads - casting number 6272990. These heads have had extensive work done to the exhaust side as well as the intake side being cleaned up. They have been magnafluxed and there are no cracks. They look grey because they were bead blasted - they are not painted. Heads are located in Boise, Id. and shipping will be paid for by the buyer. $450.00 for the pair. Not interested in splitting them up. Might be interested in trading for a complete Place Diverter with control handle and cable for a Berkeley pump. Thanks for looking.
