heads coming loose

This is my mildly modified 3.3 bus motor. The motor winds out so fast with the 5 speed I've never gotten past 1/2 throttle and .8 boost.
When I checked the head stud torque at 1,000 miles, the head stud nuts felt like they had about 10 lbs of torque. I re-torqued them down to 38 lbs. I recently re-checked them at 2,800 miles and again, the nuts feel like they have about 10 lbs of torque. I re-torqued them down to 30 lbs.
Not sure what's going on, or what to do. Are the studs being pulled out of the case?
