If you're set on a more streetable cam, I would do something like this:
Single pattern, 236/236, 112 LSA, .650"/.650" with 1.73 RR, based on Xtreme Energy lobes.
This is more of an aggressive lobe than your 288R cam, plus we're stepping down in duration. Advertised duration on this one is 274 compared to your previous 288. That raises DCR up substantially...so I wouldn't even think about running the closed chamber heads.
This is still raising flags in the back of my mind...and I would still advise you to switch to a hydraulic roller. It's just a lot of "inconveniences" for a sub-6000 rpm street car.
