I’m hip. Guys live and die by CFM but the W2 will out horsepower ANY conventional head. Period.
The W5 is better than the W2. I also no longer discuss flow numbers on much of anything because guys who only port one type of head never see what other heads do.
And then they never dyno anything. It’s frustrating for sure.
If Chrysler guys would stop buying OE based cylinder heads maybe we’d get some more offset rocker heads.
Guys snivel because they have to buy a half set of rockers. And headers. And a manifold.
It just makes no sense to me.
