I tend to agree. If your starting with zero parts in your toy box. I think your under funded. The heads I had IQ52 Jim Laroy do for my build of 650 hp, I have $3500.00 in them with his work, the new parts and the new castings!
I bought a low hrs 470 short block at a hell of a good price and I still figure I'll have 10-11K in it, dyno'd and drop in ready.
