I can vouch for the a/c output in DirtyLarrys truck. You can hang meat in there. Thats with 134a too. I do remember that he did install a hot water shut off valve (manual ball valve) on one of the heater core lines as the stock a/c setup still has the hot water ciruclating even with the a/c on.

Larry and I were talking about the hole he had to drill just a little bit ago. It was on the passenger side head. Best thing to do is to bolt the pass side bracket to the engine and mark the spot on the head where the bracket hole lines up to. Then remove the bracket and carefully drill the hole making sure to be level with the head top to bottom and side to side.

You only need to drill the hole if you have older heads. The later heads have all the holes in the right spots for the serp brackets. Your iron eagle heads should have all the holes too.
