Mogegg, I don't know where you are in the world but there are several places that make bespoke pistons in the USA. Accralite make them in the UK. I've used JE pistons in the USA and from the UK you need to go through an agent. I used Cambridge Motorsport as an agent I think they are others. For four pistons they are not that much more expensive than of the shelf ones.
Cheers
John.
