Absolutely, the rotating assembly needs to balanced, with the balancer, which you should get new. Take the flex plate (also new), rod bearings, wrist pins, locks and rings for the balancer too.
I’d recommend a new set of rockers (PRW work I think?), and you may have to get a correction kit from B3 for good geometry…check first of course.
Get the heads checked…probably need a valve job and have the guides honed proper. May need the heads surfaced.
Read the ring gap instructions for the hyper pistons, they like the top ring to have some decent gap.
That cam will want some converter. As such, might as well go single plane unless you already have the dual plane.
