Sorry, I dont feel like searching all over the internet just to get numbers that I would doubt, since specs like this seem to be different from almost every resource.

So, does anyone know the valve diameters for the

B18A/B and B20B/Z heads
ITR
GS-R and B16A

Thanks

B16/B18C VTEC head: 33mm intake and 28mm exhaust.

 

thanks
