Anyone do this yet? Is the 11.2 compression too much for street cars? I've seen that SDPC>>>>>>> offers the 63cc version head seperate. Just wondering if this is a good "bang for the buck" upgrade? Any info is appreciated. I'm not looking for a monster head/cam, just something that stands out ahead of most on the street/road racing... Thanks guys....

 

I'd remember the port volumes are huge on those heads. Not necessarily best for street, maybe road racing.
