Since I posted this question, a bit more research lead to spears site. But I’m in the UK, so add in import duty & 20% taxes & their kit is expensive, plus no idea of the weight of the pistons. The Wiseco 64 or 66 300 pistons at 12.5/1 compression would work.

The other thing I found on sears is the high comp stock bore gasket that may be a simple solution for a bit more torque !

FYI Nikasil or other SIL rings will work fine on an iron bore, but NOT the other way round.
