Here are the finished heads. They have Ferrea valves with 1.77 exhaust. The exhaust flange was pretty gouged up from the steel shim gaskets. They had to remove .025 to make them flat again. This is why I never put steel shim gaskets in anything. The heat cycling causes the steel shim to act like a cheese grater. If seen several sets of Pontiac heads with the exhaust flange buggered up including round port heads.
