Joker valves

[Manateeman]

We are rebuilding a Wilcox and Crittenden Skipper 2 head. Page Belting in NH can supply the cup leather for $ 20.
The closest joker valve is a Groco, H-27-A with a Jabsco 44-101-1000 seal .Or...
We could add a gate swing check valve but...isn’t there a better way?
We could fabricate a bronze plate to fit other joker valves...which would be best?
Or, could we cast one in silicone?
We’ve made bronze castings but never rubber material.
Anyone have any experience or DIY references?
Thanks in advance for replies.
Happy trails to you
Mark and the manatee crew.

In reference to the post above by GordMay:
On page 16 of the PDF, they describe the installation of the base plate as being the most difficult part of the re-assembly operation.
My solution for easy installation was to get 3>4 bolts and saw off the heads, then by threading the headless bolts into the base casting it provides an "assembly jig", you slide the base plate over the bolts down far enough to start the threads of the flat-head screws, then remove the headless bolts and replace with the remaining flat heads.
The spring is easily delt with in this manner, and you're not fumbling around trying to line-up all the holes, nor risking the misalignment of the base gasket.

Bowdrie gets a high five from the manatee crew for this post.
We’ve done this job a number of times and struggled to do this step.
Elegant solution. We’ve used line up bolts before but sometimes you just don’t see the easy way out.
These are fantastic heads and worth rebuilding.
Now all we need is a way to copy the original joker valve.
Happy flushing.

You could 3D print a replacement joker valve using flexible fllament.
