They are talking about 25 heads. Now I have been told that if you have good flow you can compress but if you dont have good flow then you can not.

You guys who are using the 10 & 11 Heads I would imagine your motor flows preety well. Now are you guys changing the valve angles and making them flow or porting a certain way? It almost seems you guys are "shaving" the "eybrows" for more flow to me....

The 12 hp head flows better on a flow bench but more importantly it works better on the track Thats what matters not the flow bench numbers. Had an 11hp head motor flow more but it sucked on the track. What and how I do inside the ports is not open for dicussion. BUT when built right ( to my liking) the 12hp head runs better. Thats for me and what and how I like personally. Wheather it works or is liked by billy bob down the road I cannot say. Those running my motors have had no complaints about running up front as of yet!!!!
