1650 Gas head

Does anyone know the chamber volume on a 1650 gas cylinder head and the valve size?

The 1650 gas has concave pistons, I can't remember the valve size off hand

If you have the head take a Syringe and start filling the chamber with rubbing alcohol and keep track of how much you put in. Alcohol doesn't have surface tension like water does. I should have just sold you my 88. It has tip bars, weight brackets and a pulling hitch. Engine has 880 valves, 1650 manifold , M&W pistons and a Bullet cam.

I bought an 88 puller from over by Marshall mn. Owner didn't know exactly what the engine was so I pulled the head off to see what I had. I have all the necessary equipment to properly cc a cylinder head at work but don't have a 1650 head to verify the chamber the volume. I am trying to see what the difference would be in compression ratio if I put the 1650 head on the current set up I have now. Prolly just gonna work over what I have, since it had issues, then tweak it a little bit and run it this summer. Have plans to build different power plant next winter anyway.
