Surprisingly enough, heads are likely fine. that sleeve or the whole block may be done. 
I am definitely going to flow test or swap injectors before rebuilding either block. |
Ouch!
I remember a similar picture of the piston in my 1st EJ257 that let go on S-Squared's dyno (I think Aaron took it w/ his cell phone). Mine was probably caused by a lack of fuel due to the missing Walbro that wasn't installed (800cc injectors are pretty worthless with a stock WRX fuel pump trying to supply them). Are you leaning towards a bad injector at this point?
That makes me consider pulling my 800cc injectors and sending them out for testing, or maybe just going back to the 675's I've got. Or perhaps just getting something in an 800cc size other than the super laggy PE800's I've got that are impossible to tune for in the Hyrda (the lag in the PE800's is larger than the largest number you can put in the latency table, meaning you have to set the latency 20% shorter, then modify the fuel table).
