Just pulled the head off and found this, has anyone seen a piston like this before? Bore is scored and looks like the ring has picked up, still can see some coding on the piston.

I see the problem. Should be a Coke piston. Don't you know that 'things go better with Coke'
An old slogan, probably before your time.

traditional pipe benders and capascity are generally for Thick walled pipe. You use thin wall stuff.

tube bender vs pipe bender https://www.youtube.com/watch?v=fWiXTr-6N4I
There was a guy in Nelson doing Featherbed Norton replicas who simply rang up Autobend in ChCh and ordered up a 'kitset' of bent tubes he'd already sorted with them...Autobend are one of the few in NZ doing really good mandrel bent stuff in a good range of sizes. I've used them occasionally. Not that cheap but good.
Can't see all the stuff Husa has posted - but the simple bender from Aliexpress is quite similar to what I've got. The only caveats I'd make is that we don't have metric tube in NZ - it's all still inch. And the ability to do 1 1/8 too is bloody useful as inch is really too small for most of the "classic" frames.
If you do get something like that I can see someone's CNC being used to make formers for bigger tube. And mount it on a decent piece of RHS about 100x100 bolted to the floor and about waist height.
