Yes it has 1.70 / 1.44 valves.
I bought a mild /6 build and the head was already done with the bigger valves,some bad machine work was done, valve were not centered to seats...
I do not know if Justin still has the numbers but originally flowed worst than a stock head.
Justin ported it and then was sent out for a valve job and to replace the valve springs.And now he is reporting final numbers.
The head has not been milled just resurface,I believe that it cc'd at 54cc.
