Slant 6 power?

why did you go so big on the exhaust valve? 1.44 would be plenty...

The 302 cubic inch 1968 Chevy Z-28 has virtually the same per-cylinder displacement as a 225 /6. (225/6 = 37.5; 302/8 = 37.75.)

Chevrolet saw fit to put 1.6" exhaust valves in those motors, and we all know how those engines run.... Bigger valves USUALLY make more power.
