Who are you thinking of building it?
I'm not using DI anymore, so when I blow up mine my options are a built n54 wity plugged DI ports (same as now although its otherwise a stock block), built n54/n52 mut, built n52, LS swap, dump the platform. Vac do a billet s54 which I guess I could throw in the mix.
Galloway looks like there pretty capable on the machining front but I haven't got first hand experience with local machinig/building so keen to follow how that works out for you.
im not sure who im going to get to do it yet. have asked a few people and had a few different recommendations. head torque seemed to be the most recommended local place for headwork but still undecided for the bottom end.
i plan to go stand alone ecu and PI only before putting a built motor in but i guess we'll just have to see how long the stock one lasts.
