Panic,(and others),
Yes, that is exactly where I mean. It appears that you can mill that bulge out if you don't go too far. I don't know how far the speed shop went, though. It does look as though you could make the chamber wall the same thickness as the thinest portion, paralleling the water jacket's inner wall. As I recall, that's what my head looked as though he had done.
The numbers were higher than I thought they would be, also. He, (the speedshop operator/machinest) said that the flow would support 300 horsepower, if, one could get the engine to rev that high.
He also agreed that the flow could be better if there was a more gradual short side radius leading into the valve seats. My ports are virtually flat, with a very small radius. \:\( Lump ports, anyone?
In any case, it's academic until I am able to solve my rocker shaft alignment problem. \:\) Toolman


The main problem in the world is that fools are self assured while the wise are full of self doubt.
