Anybody have pics of 426 Max Wedge Stage ll and lll heads

I think the tulip valves were one of those “seemed like a good idea” things.

At least...... they don’t work in those heads on the flow bench.
The floors on 286 heads are flat as a pancake, and the tulip valve is just in the way.

I remember years ago, a guy who was from down under who used to port heads tried them in some 906 heads.
I don’t recall how much it was, but they really knocked the flow down on the set of heads he was working on.
