I just got off the phone with a guy that is very well known for quality head work in the area. He said that the DOHC ZC head is already very effecient, and that I wouldn't notice much of a power difference by porting the head. Would it be worth it to have the head ported?

I'm just looking for some feedback, I may have to go to a more ZC specific board.. I'm in the process of building the motor right now, about 10-10.5:1 C/R, I/H/E, cams, cam gears and maybe a 50-100 shot of nitrous somewhere down the road. Daily driven, but I plan on doing some road course/Auto-X this upcoming year. TIA!!
