School me on W2 heads.

I will go take pictures of my w2's and strip dominator that has been flowed with a piece of wood and epoxy .
Got them from my neighbor an x ss racer .
Heads have new valves no springs .

Would like to see that,
I remember using "popsicle sticks" in the Offy port-o-sonic manifolds with std. 340 heads.
Never saw any used with W2 stuff.
Thanks
