What cam should I get?

Yes the flow does not improve over a .450 lift but if you go say .480 it will flow max. a longer amount of time. You just want a good sounding idle I think you be happy with comps HE 268 or even a HE 260 but I would get the HE 268, oh it has .454 lift so it should flow great. I do not like 1.6 rockers for a street motor, puts too much stress on everthing, you want a bigger cam than get a bigger cam, those lobes are for a 1.5 lift.

The reason I stated .450 lift is because Hughes Racing says "Maximum lift with stock guide height is 0.450", more lift requires shortening the valve guides. " So I it sounds like I'm stuck in the mud. Does anyone know that this true for sure? I mean it states that but I'm not completely sold on that. Another words has anyone had trouble installing a cam that has a higher lift than .450? I would much rather hear someone say that they had a .454 lift came for years and didn't have any trouble with the guide height. Another words I just don't want to tear the heads off! LOL! I would much rather slip in a bigger cam.
