was it only cali that got the egr's on the 12a? i dont recall there being any EGR's any of my 12A's. i have "federal emissions" versions of each series; S1, S2, and S3, and there is just a blank non machined spot where there EGR's are on the center iron of later motors. i think there is a difference in the relation/covering of the air injection port and intake manifold between the series on the side of the center iron, but if your running a header then it shouldnt matter. overall tho, it should be a pretty strait forward swap.
