I found a couple rebuilt 2.3 heads online and was thinking of running the crower springs-retainers and either the stg2 or stg2 turbo cams.
You should be able to bolt on a 23 head. Massive performance has cams for the '08+ motors. Are you going to add a turbo? Do the rebuild heads have 1 piece ss valves? If your going turbo, I'd probably run the 20 head. If not do a 23 head & go for the stage 1 cam. The ports are bigger but they both have the same size valves. I;m not sure of the cc's of each head. The compression is higher w/ the 20 thou. Hit Massive up.
