It sounds very much like my car before I retired my SD heads and went to E-heads. Compression bump will help and looking at the pictures you're running those pistons about .020 out of the hole. I expect you'll see that right around 470 hp and enough torque to make you smile a lot. Just a guess. I'll be curious to see the numbers.
