All Pro's should flow close to 300 CFM out of the Box, unported. Once you turn a good handporter loose on them there is no telling where you can go. They come clearanced for Shaft Mounts, Bigger Springs, 3/8ths pushrods, yadda yadda yadda. Also you can get the chamber size any way you want. They're about $1700 bare depending on who you buy them from.

Rob,
Is the valve guide spacing and valve angle the same as stock? Also, what size valves and test bore were the sample ports flow tested with? Is the spark plug in the standard location and can stock rocker arm assemblies be used?
Thanks,
Richard
