Ok..... so for those of you that didn't see the follow up of the posting "what's holding her back?", looks like I'm doing a full rebuild on her earlier than I thought. So with that being said, I would like to do this right the first time. I need thoughts on how I should build this to give me the most power, but also the most longevity out of this motor. I like the idea of the cam grinding and the porting, but I really don't like the idea of going to the extent of oversize boring. I would like to keep the stock engine size, just want it to "be all it can be". So if you guys have suggestions on places I can find the parts to make this happen, or places you recommend the services for porting or shaving the head, I would love to hear them. Heck I was even thinking about picking up a whole new head for the hell of it if I could find one cheap enough.

Pennyman, I still plan on calling Oregon Cam Grinders. I checked out their website, and I think that they will be perfect.

Thanks everyone for all the great info so far! You guys have been a major help in getting me going in fixing this D50 Sport up.
