Match cross sectional area, oh my!
Its a less than fair comparison, with "numbers" going towards AFR, however the ET heads out performed them.
Please, if at all possible post a graph, I'm guessing that the lower end will be greater too. |
I would say so too. The AFR's are great heads, but you have to realize that cross sectional area is the most overlooked topic when it comes to heads. AFR actually has more cross sectional area on 205 cc runner on a 15 degree head than the 215 cc ETP heads.
These ETP heads are just engineered to make power everywhere and that's what they do.
