Well since it once had a MP 590 in it, before the MP 533 I'm sure that would fit again, if all else was the same. Wouldn't be a bad choice at all IMO I like the 106 LSA for your engine combo. Install it around a 100 ICL

If you want something more modern, maybe a hughes 6872 It has less intake duration, 268 @ .050 compared to 271 @ .050 that the MP 590 has, but more lift .629 But with your heads the Extra duration of the MP 590 and 106 LSA, might be the actual better canidate then the more modern cam Hughes. Some will say, Roller all the way. Not a bad choice either.
