Yep, those will work. I'd use something like a 110315-10 Howards retro hydraulic roller cam with 91164N Howards hydraulic roller tappets.
You can order the cam from Howards with a reduced base circle to clear the 5.7 rods, or you can use a full base circle cam and Scat 25700P rods. You can also use stock Chevy rods and grind some material off at or near the bolt head to clear the cam lobes, but I don't advise grinding on rods.

These springs would work.....

Estimate SCR at 9.2:1, DCR at 8.33:1
Use a steel shim gasket to set the squish between 0.035" and 0.045". Gasket thickness added to piston deck height equals squish.
