The 49cc Dart flows the same as the 64cc head . The valve is unshrouded the same in both head casting's . I can't speak about the Pro head's , but I would assume the same would be true .

I talked with my new machine shop guy and he talked to Topline and they dont even have the 50cc heads made yet. I'm going to go with the Darts instead.

Scoot the 50cc Pro line are available, I know a few people that run them. I called DART a few days ago to get a part number from them to buy the 49cc assy. The number they gave me didn't match what summit had, their tech person was real dry and didn't seem like he wanted to answer the questions I had. I'll give them a call again, give them another chance. Maybe he was having a bad day. Good Luck
