1st time porting 308

Just cleaning up the casting can go a long way to improved cfm (aka quality cfm.) i wouldn't spend much time in the guide boss area, were it's attached to the bowl area. You just gain port volume with no cfm gain.

I haven't flow tested these heads but usually the pushrod pinch area is not as big of a issue or problem as it looks. i would leave it alone, as well as the ssr(short side radius) for the first try.

With all that said, it looks good.
