04 05 stock valce measurment?

[Sollie1986]

I have an 04 head and it have been previously worked. I just measured my valves and they are 36.6mm and 33.6mm.

Do you round to the nearest number and therefore they're actually 37mm and 34mm which would make them +1 oversized? What does the stock valves measure?

Thanks for any help.

Not sure where you got 34mm exhaust valves....biggest i've ever seen are 32mm but stock is 36mm and 30. Also they dont measure in half sizes either. A 37 or 36 will measure just that. Sounds like one off customs
