Is the head on the Si and the RSX Type S basically the same with the exception of the rocker and cam assemblies. Could you install the rocker and cam assemblies from an RSX onto the Si head. I don't have a RSX head to compare it to.

 

does the K20A3 head have lost-motion assemblies? if not then you're gonna need the K20A2 head... there are other things to consider too, for example the K20A2 has a higher flowing head with different valves & valvesprings

No, there are no lost motion assemblies on this head. The reason I was asking was I have a 03 Accord head which is basically the same as the Si and I was wandering if it could be used in a performance application, with of course new valves and springs. I have never seen an RSX-S head before so I had nothing to compare to. I guess I can scrap that idea. Thanks for the info.
