Aluminum Head Identification

Third thought.

I remember the exhaust having a D port, not the square port.

I'm thinking that's a very early W-7 head and I'm sure Ritter could help you out IF you can get him on the phone. I haven't talked to him in years but he always helped me out.

I have access to a W-5 and W-7 and I can get to them next week. I know the 5 has not been machines for guides or seats and I don't remember how the 7 is but at least I'd see what exhaust port is in it.


Come to think of it, I don't remember the 7 having that chamber in it. I know I'm not the only one who hates it.
