12 and 13 bar is a big spread in compression, but you did it cold so its not unheard of. I would expect 13 bar or higher with the engine warmed up. Did you dyno the engine? or are the torque peak numbers generated by the butt dyno. The header might be too big for an earlier torque peak.
If they really are super cup cams you should feel the engine come on the cam around 3000 rpms, even with the big ports.
