Camcraft offers a powermax head that is ported.

"Utilizing new World Product castings and stainless steel valves, as well as lots of flow bench time, we worked with a leading engine builder to develop a head configuration that flows 10% more air on the intake side and 15% to 18% more on the exhaust side. This was accomplished without enlarging the ports or valves so as to maintain maximum velocity, which is critical to low and midrange power where these engines are typically run.

Heads are machined on a Serdi head-machining center for maximum consistency and performance. All new castings and stainless steel valves are used as well as new valve springs, retainers, valve seals and valve locks. "
