With 8.5 SCR, your upper limit on the intake side will be about 210 degrees @0.050" tappet lift. The exhaust numbers don't mean so much. You could do a 210/210 or 210/220 or something thereabouts, just keep the intake at 210 or less unless you want to increase the SCR, then you can run more cam.

As far as your two choices, you probably won't be able to tell the difference in the seat of your pants.
