Good question! We use an advanced TPV material that is far superior to the silicone pieces, and the overseas stuff. It's OEM level of material and should last 100K miles without issue.
Another thing to note, is that this style flapper valve (originally designed and used by BMW) was made for installation on vertical baffles. Never in a horizontal application. The aftermarket got a hold of it and right or wrong, put them on everything. If you look at horizontal installs, they sag open. Not only that, but because they sag open and are installed incorrectly on a horizontal surface, the heat causes them to take a set, in the open position. This can happen after only a couple of heat cycles, rendering the flap valves functionally useless. When used correctly on a vertical surface, they only open 1-2mm.

Agreed.

We have gimbal plates that we use for this exact thing, but they are for EJ engine/pan testing. We tip up to 60°, a few degrees doesn't really do anything. The lateral loads need to be REALLY high to actually surge into the heads.
