im planning on building another d14 head with springs, retainers, cam, 3 angle valve job, and a port
i am going to replace the valves in the head and was wondering if it is worth wile putting in 1mm oversize valves. obviously i will get the valve seats cut to suit. so is it worth it?
cheers

No ,use stock size.

Re: oversized valves
bigger valves reduce velocity of the mixture?
Re: oversized valves
Sure. In a small engine that would not compensate !
