Missed on this combo?

Well I took them to my machinist/dyno guy/jedi engine master. He cc'd them more precise and they are a full 72cc.

Also, something I didn't notice, the exhaust port is raised .200 compared to the Eddy. And shaped MUCH better. My TTI'S are pretty tight. I hope things dont change down there...He was actually REALLY impressed. I mentioned maybe getting one flowed and he said don't bother. Told me there's a reason he sold both his flow benches. Pretty experienced guy. He thinks they may be the casting that Promaxx is using.

Really gave me some ****....."All this good stuff and all your time in this motor, it's about time it gets some REAL heads." "Money well spent." Geez, I had to sell one of my AR 15'S AND load a thousand rounds for the guy. He thought I was kidding...

Back to the milling, now you guys have me thinking again. Man I don't want to screw up my combustion chamber. I also cannot tear it apart again. After this upcoming dyno session, it absolutely has to go in the car.

Mill, don't mill.....mill, don't mill......
Really we are talking 1/2 point in compression. Using Summits calculator it's
11.45:1 vs. 10.96:1. Doesn't sound like much.
