Long valves on W2's with .600 lift?

I've run as high as 2.100 on W2 and W5 stuff.

It's not worth it unless you really need to net .800 lift and can fit that on a reasonable lobe for your RPM/displacement.

The best I could do is net .750 lift but that was on 340 inches and I just couldn't get more lift without going to a lobe that made me cringe. And that used to be hard to do.

So for the lift you are wanting if you can get 1.900 installed you should be able to get what you want easily and not have to fight the geometry to make it happy.
