Also if the heads had porting work done to it, it's worth checking they've not gone too close to the pushrod holes with the inlet ports, this can then suck oil into the engine.....
Another good look at the inlet port showed that there was a very small hole indeed. The maker went through the wall so on cylinders 1 and 2 he must have gotten oil in the mixture when the oil was getting warm.

New piston rings that fit, check. A better hone finish, check. Cylinderhead fixed, check. Starting up tomorrow and hopefully a nice track day Saturday...
