I am looking at a set of 5.3L heads with casting # 706 to start my H/c package with. I know I will have to go through them and plan to upgrade to chromoly pushrods and ls6 springs ect... Are these good heads? I hear a lot of ppl using 5.3 heads but not much on this cast #. The came out of a 2005 tahoe. Any info is greatly appreciated.

Well to my understanding, If i just bolted them up I would gain because I would have higher compression due to smaller combustion chambers but the flow would decrease causing no real gains. I would want to put in bigger valves right?
