FYI,
The Trick Flow valley plate is back in stock at Summit. O-ring seal on the removable center cover (for lifter maintenance, etc.). up
Trick Flow® Valley Plates TFS-61600830

And Summit shows 0.700" max valve lift with the solid roller heads, TFS-6161T784-C01. And if you look at the PAC springs that come with them, you can likely run a tiny bit more. But check actual installed height, coil bind, lash, etc.
