RHS or EDDY

i would keep the ported J heads on a street machine. heads are really expensive and it sounds like you would be swapping a ported j for an as cast la-x yours should flow better at this point. plus don't you have to pay extra for the 2.02/1.60 valves in the rhs heads? i say leave the heads alone and work on compression and maybe more duration on your cam so you are taking in more air
