440 MP 528 cam eddy performer?

I'm building a 440 for my Duster. I have 10.5:1 compression TRW pistons, 2500 stall, 355 sure grip, 850 thermoquad, tri Y Shumacker headers. isky adj rocker arms 1.5:1

I am thinking about using the MP 528 purple shaft. 284 int./284 ex. advertised duration 0.528 in. lift 2400-6600 rpm operating range.

I know the Eddy Performer rpm is the best choice, but I would have to use an adapter plate for the TQ. Would the Eddy Performer with the spread bore pattern work well with this combo. Also how about the spread bore Holley Street Dominator???? any input would be helpful. Thanx
