Default NCY 62mm Cylinder Which Head Size?

Hi,

So I am considering the NCY 62mm for my gy6 150cc. I am also considering a 2-3mm stroker.

The question is that NCY only makes a 61mm and a 63mm head. I am wanting the best performance and wondering which head would be best for the 62mm cylinder.

I always get the 58.5 chamber head for more compression ratio

Sycarms,

Have a 62mm NCY ceramic Cyl on its way.

So you fit a 58.5 on the 62mm?

What about a 61mm on the 62mm cylinder?

Are the valves big enough to create performance with this big of bore?
