bad day on the madien voyage

After one whole year of working on it.....I took it to a buddy who has a repair shop yesterday. He did a front end alinement on the 68 Brracuda and gave me a NYS inspection. Beautiful day here in NY so when he was done I took it out in the road for its madien voyage. It ran better than I expected and handled much better than I expected. I put about 50 miles on it and was living large. Today another friend came over to see it. I started it up and popped the hood and almost died. Liquid running down the passenger side front of the block starting at the head gasket. I am sick. This motor was broke in on the dyno and appeared to be tight. I've got less than 70 miles on the motor. Tomorrow I am going to put a torque wrench on the head bolts and cross my fingers. can somebody tell me the torque for the heads on a 340. ?
anybody have any words of encouragement?
