3 weeks back or so the truck started running rough at low idle, checking into it we discovered a broken exhaust spring. These were the original springs and we decided to change them all to new ones, with the heads in place. We started on the truck at about 8 am and by using a air pressure manifold, we were able to use air pressure to keep the valves up while removing the springs.

Took about 6 hours, the worse springs to get to were cylinder 6, because it's almost directly under the heater core. Instead of using a spring compressor, we used an open end wrench to press down on the springs so we could remove the keepers. Glad this job is over, took about another hour to set the lifter clearance and tune in the carb.
