Help with my first engine build (5.9 Magnum)

Thanks everyone, I decided to go with the Hughes 1199 spring kit. Camshaft and re-ring kit are also on their way.

I'm going to attempt doing the cam bearings myself, looking for a tool locally to rent now. Hopefully Oriely's or Napa can come through. I will post an update soon with the progress! My plan is to order 2 cam bearing sets... just incase... you learn by making mistakes right? Lol...

Thinking ahead, I have heard that some people wash their block with soap and water to remove dirt and grime, then quickly blow it out with compressed air. Is this a safe practice? I don't mind doing it, however I feel like it would cause flash rusting? Have any of you done this with success? All my local machine shops are booked out over 2 months and aren't taking on any jobs, even for hot tanking...
