The 5.7 (non-VVT) blocks are a good choice. Just be sure to sonic test the bores. It took me 3 blocks to find one I felt was acceptable. There was obviously quite a bit core shift when these were made.

As far as boost limits on stock head bolts and gaskets - we've taken a completely stock 6.1 engine to 28psi with no sign of head lifting. This doesn't mean I'd build a purpose built engine with this configuration - just relaying the strength of the stock setup. Go with head studs and Cometics.

Modern Mopar Forum is a good place for full tilt Gen III Hemi info if you don't mind the drama.

Here's a link to a thread on pushing a stock 6.1 to the limits:

What I'm looking to build wont use much boost.. maybe
15-20 psi max.. it'll be a stand alone injected with
either a single or twins with intercoolers.. just
a street/strip ride that will only run 10.0 in a
2900# Rampage... I'll most likely get the engine in
and running then mock up for the turbo/s and see what
will fit... nothing fancy for power

You wont need boost to run 10.0 at that weight with a Gen III Hemi. We have a customer with a 3700 pound 4 door, 7L running 10.30 NA. There's several others out there doing the same or close and many daily drivers weighing 4200#'s running high 10's NA.

Yeah I know but when I can get to a few tracks I
want to turn it up to see hat it can run.. mainly
the turbo will be for looks and some fun... plus I
want to run on 87 octane for the street and some 93
at the track... it wont run much boost.. MOST of the time

Yes it is. Its just an oil tunnel that merges the rear oil drainback at the rear of #8 to the drainback between #6 and #8. Even if you went through, it would just drainback at the breach instead of through the 6-8 drainback.
