my first rebuild...I set the timing using the joe reeves method in secret file...I mixed up my gas at 25-1....3rd crank and the motor fired up and sounds great,I let it run for about 15 min. at 1000-2500 rpm.....motor never skipped a beat and sounded great the whole time...I want have time to take it too the lake till next weekend....when should I retorque the head bolts...what else should I check after the 1st run or keep and eye on.....engine temp. seem good I could keep my hand on the heads for 10 sec.s or so and the temp. stay the same entire time
