Does anyone know what the included valve angle is for the YB head. i have the early 2WD head and I mention that only as I am not certain if it changed at all over the years it was in production
I am trying to work out some clearances and I haven't got any of my bits here to measure.

Ok, I'll rephrase the question!
Can anyone tell me what the included valve angle for the YB head is?

So then, the angle is 22.5 degrees to a vertical line through the centre of the head? Yes/No?

I seriously hope your wrong about these Danny, God knows how long it will take to get another set done. I wanted to be up and running for September.
