With the bottom end sealed up, B&B's Dave Radomski installed new dowels on the decks and laid on the new Air Flow Reasearch 165cc cylinder heads. In a previous test the heads flowed 250 at .600-inch lift on the intake (28 inches of water) and 191 cfm on the exhaust. The heads are CNC-ported, feature 1.90/1.60-inch valves and should be a perfect match for our "E" cam and GT-40 intake. View Related Article
