Hey guys I was able to source a new in box a13 h62 head. I am trying to find valves for it now. The h62 uses a14 valves correct? And a14&15 use the same size also? All the valves I can find are for the a14&15 but they say the length is 3.931" -99.84mm. According to the tech wiki a13 h62 uses 103.5mm I'm guessing these valves do not interchange correct?

Also I made a mistake in Machining my flanges. I machined to fit a14 instead of 13 by accident can this be ported out or will I hit a water jacket?
