No, there would not have been enough heat to do anything to the head. The HG was/is fine. The leakdown test confirmed that the HG did not leak. I plan on getting another TQ wrench anyhow to replace the POS I have. I always torque the head studs to 105 with ARP lube to assure I am torquing them tight enough. I also stood there and made sure he torqued them in the correct sequence (60ft lbs first then to 105). HG was not a problem but the torque wrench is on order right now and I should get it in at work today
