2.3 head differences?
I made a post on FJ and didn't really get a real answer. What are the differences between the 2.3 head and the 08+ 2.0 head? Are the combustion chambers the same size? are the ports really that much better in the 2.3?what all needs to be done to run an earlier 2.3 head on a 08+ focus? 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.
