Hughes HUG1110P valve springs- anyone use them?

The specs look fine to me for that level of camshaft.
Just be sure to not short your installed height and maybe
even put them in a bit more (1.68 to 1.70) height,

As with any HP engine do not let it idle for extended
periods, especially when new.

Be sure lifters are rotating as the new cams and lifters
are Chinese plastic junk.

Just my .02
Your mileage may vary.
