I have a Twin Cam Weber head in excellent condition. I believe it to be an early head (pre big valve) and it has clean combustion chambers, all bearing caps and exhaust studs, is flat, and appears completely stock with regards to any porting.
I obtained this head from Richard at Europa Engineering to convert my stromberg engine to webers, but decided instead to use a brand new head to build my race engine.
