Some 5.9 roller cam help from y'all please
I am trying to figure out what box you got your EQ heads out of that limit you to .470" lift.
I ordered my EQ heads with springs installed for to go with my 224/230 .513" lift, 110 LSA, custom Comp Cam roller cam. I basically recreated the XE 268 in a roller cam. It has a nice idle at 800 RPM. It is probably a bit more then what you are looking for.
I would think something 218/224 or 212/218 would be a good fit. When in doubt, especial where street manners, go with the more conservative size cam.
