That is one of the best analogies I,ve heard to explain this. Aluminum material and small chamber does not necessarily mean better. The w2 was way ahead of its time and even today there are still only a couple of other heads that will beat it.
AMEN to that. The open chamber in the W2 is FAR better than the W5 chamber and that chamber takes a TON of work to fix. And then it's only as good as the W2 chamber, barely.
There isn't a standard port head out there, with the exception of the 351C head that is better than the W2. Nothing. If someone started making the W2 in aluminum and making the shafts and rockers for it, the small block stoker world would revolutionize itself.
