 After rebuild with high compression pistons and other HP upgrades, head gasket leak after 5,000 miles from cylinder 2 to water jacket. Does anybody know if head torque should be increased with hi compression engine?

Upon head removal torque was ~80 ftlb (slightly less than spec). No uneveness between cylinder sleeves or outside or block rail and head was milled flat prior to install so no obvious reason for why leaked other than maybe the torque needs to be higher. Head gasket was the Delta Motorsports product.
