W-2 Head questions

I know you don,t like books but in the old Larry Atherton book they talked about the w2 versus the Cleveland with it big ports and good reputation. The Mullen prepped w2 did not quite outflow the Cleveland, but they claimed that the w2,s dynamic on track performance out did the Cleveland because of the better short turn
Of the w2. That book also emphasized that flow numbers are not everything and that the w2 design was very well track tested to perform all around, but now the Cleveland was not your run of the mill head either.


Yep to all of that and a HUGE AMEN to not looking at flow numbers as the end game. Buying a flowbench was the biggest eye opener in engine build I've ever had. The flow number is about the LAST number I look at any more. When I sold that bench, I gave the guy my entire file of flow sheets. He was a bit pissed because almost half of them were numbers from say .300-.500 in .050 increments. Some were just one lift number with half a page of notes. He thought I wasn't doing it right. Hopefully he learned his lesson.

I did keep all the reverse flow and odd testing sheets I did for myself, so I still have those.

I can say that a set of well prepped W2 heads will out perform most of the stuff out there today with any name on it. Especially when the OE valve angles are maintained. And the ports aren't raised.
