Its not hard to make just people who would make it manually would charge a few hours of labour, and although a CNC machine would do it faster the machine time is more expensive.
Surely someone knows someone who has acess to a drill press and a mill.
just need to to-scale print out the footprint of the plate and mark it on the alloy. then drill the headbolt holes with a drill press and then mill out the cylinder holes. it doesnt need to be perfect. as long as is in the ballpark it will do the job.

I am happy to do the work, its just a matter of being allowed machine time.

To confirm (simply) is this particular plate setup for achieving/maintaining "factory" like specs or accomodating oversized pistons etc?

It's to maintain perfect cylinder "roundness" when heads are torqued down for best ring seal. Any1
Correct me
If I'm wrong? As when the heads are bolted down the cylinders can warp and go out of round.

Yeah got that bit but that applies (is desirable) regardless of the selected bore diameter does it not?

Cool so I'm assuming standard bore diameter in the context of this plate...

Yep true, I guess I could have asked my question a different way.

I.e. what pistons are being used with the build that this plate was initially conceived for.

Bores in torque plate can be made significantly oversize if needs be. The bores in the plate don't do anything besides let the hone through. It is used just to simulate the head being bolted down. So you could theoretically machine your block as oversize as you could go.

Yep already clear on that... will find the corresponding build thread and enquire further there about piston choice etc, cheers.

this plate has 83mm bore holes so it can be used with up to 2mm O/S pistons. but it can be used with STD 81mm bores as in the pics above

Adam, hopefully making this before Xmas. As it will be a multi use part, would it be advisable to press some steel bushes into the bolt holes to prevent bruising by continual use? Or will that affect the torque it applies?

I wouldn't bother. none of the plates I've seen have inserts, just make sure you use the washers with the ARP studs as thats enough to spread the load
its not like its going to be on and off blocks every day. just every now and then
