Next generation CNC heads

Okay, I know a lot of you guys were interested in my CNC heads, but they were cost prohibitive when you factor in overseas shipping. I had a concern with using +1 valves in a 100mm bore, due to the possibility of shrouding. So we finished a new head design that utilizes the stock valves to help knock the cost down, and reduce the possibility of shrouding.

We ended up nailing it! The head actually flowed 353 CFM@28" and .500" valve lift. This is better than my original +1 design. For those that don't know about flow numbers, this is not only good, it is borderline obscene! I am super proud of this piece.

Some dyno testing will be done this week, and then we will finalize the pricing. We will not have numbers that are a direct comparison for a while, but we will know if the technique is solid.
