head packages vs custom done

you could also go the route of having the head extrude hone and the HPC coated...this is basically the same thing as porting and polishing just a little bit better...then go with light-weight valves, springs, etc...I know JUN makes most that stuff...with the right cam this will allow you to raise your redline safely, also a good set of cam gears wouldn't be a bad idea....hope this helps
