I'm not sure where to go from here, at a minimum it needs new pistons and rings, it probably needs a bigger bore or a new cylinder, but I'm not sure what else the heat wasted.
Edit: there was an error on JE's website, they do make +2 and +4 mm pistons for the pregen in +0.1 and +1.1 compression ratio. If I rebuild it I plan on going with the 13.5:1 pistons not sure if I would to 282cc or 265cc.

I have had great luck with 265cc. Ran the engine for two seasons of nitrous hours and hours on the dyno and still going strong.
The 282 should be sleeved. The 282 I have was just punched out. The stock cylinder is super thin now. The chamfer on the bottom is gone making it a real problem getting the rings in. I am afraid it will crack.
