this block looks nice! and if you took your drill that you made the mounting holes with and drilled out the space in between the 775 and 1366 mounting holes it would be 775,1156, annd 1366 compatible. just a thought are you planning on mass producing this block at all?? if so it would be nice to try out. honestly your temps are nit bad at aall considering 2 things, 1: your temps REALLY are not that much higher than those on skinnee labs and that was a mainstream top end block back then, and 2: your ambient temp is 10c higher than those tests! meaning your block runs close to the same as the fusion V2 if not better probably more comparable to an ek supreme or appogee GTZ if you do the math with your ambient temps.
