W2 valve size recommendations

Perhaps much taller valve is in order?

LMAO! WOW!

but like yellow rose pointed out the W2 was designed around a 340 cubic inch build, and on the stroker engines, I think you would have a hard time feeding one with anything LESS than a W2 ....

I can see why and where the short fall comes in. While it is still a capable head, the extreme cubic inch possibility can make the head seem a bit small. Earlier when I said big for a engine size, that can be normally Seen as a 408/416 or something. At this size, I don’t see a really high rpm engine or at least I should say, a properly well feed engine at a high rpm.

I’ve learned a lot here at the forum from other W2 owners and other places even though there different brand engines, (Richard Holdner for one) but the actual experience of being there eludes me for now. Looking forward to your build and living vicariously through the thread.

LMAO!
