You should get all the necessary seals and o-rings+ cambelt changed if it hasnt already been done.
I agree with thangy as well. ITR .25mm o/s pistons would've pushed your c/r past 11.5 which is perfect territory for lumpier cams. Dont look past balancing your rods and testing your rod bolts for any existing stress fractures.
Tuning is gona be the key to any higher than stock c/r setup anyways so have enough left in your wallet to get tuned with whoever you trust.
gl and let us know how you go
