B3422w5 is talking about (The Mystery) Bloomer head, a modified aluminum unit that I know not of where it came from against anyone else’s head. The head doesn’t have off set rockers. So any off set rocker head is disqualified.
If that’s the case then it’s not even close to a racing cylinder head. A racing cylinder head must have offset rockers. Otherwise it’s a street head on a race car.
