...how much would it cost me for a HRC PGM?

About £450 and 4~5hp!

Unless it's used on a full motor, as Fontyyy says, it's more likely to perform worse with an HRC PGM than it will with a stock one.

As he's found out, and others would no doubt too if they had Steve's resources (i.e. their own dyno and the ability to use it properly!), blindly throwing HRC (or Sugo or Sugaya) parts on a bike is in no way the answer.

I'm not sure if they do, but I would expect both Yamaha and Suzuki have an equivalent book to the non-F3 SS/SP HRC books, that if followed correctly will produce a bike/motor that's extrememly difficult to make much better, even with "modern" parts. I think Dave Cooper did the RGV's some favours with his heads and valves, but I bet that in reality a bike with his stuff is really just more reliable (and possibly has a bit more performance) than one built from the Suzuki book because of modern materials and manufacturing processes more than anything else. I bet a £300 ECU doesn't do that much for them!

I can see a modern ignition like the Zeeltronic benefitting an RD system that was designed and manufactured in the 70's, but not for a bike that already has a digital ECU. The first NF5 and F3 setups used an analogue system, but it was replaced with a digital PGM later, and Steve's verified the gains on the dyno. Maybe the ignition map for the Mk1 RGV is actually a bit crap, I don't honestly know (and I doubt it is), but I bet the VJ22 is pretty much exactly where Suzuki needed it to be. We certainly saw a good RGV go very backwards with Zeeltronic parts, and it wasn't for lack of trying!

We might take the piss (a lot!), but regardless of the make or model, Steve is never going to want a bike to leave his place without getting the most out of it... just as long as none of them perform as well as the NSR! (Which they never will! )
