Correct. The XER273 is a pretty good 'off-the-shelf' cam for a build such as yours. If your proposed LQ9 is actually getting 60-61cc heads, you're looking at 11-11.2:1 compression so plan to fill up on premium octane only and be sure of your tune.
To take full advantage of the heads and cam, I highly recommend looking into the Trailblazer SS intake manifold, throttle body and a good exhaust. A standard truck intake with stock exhaust manifolds will hold a set of TFS heads back like the Hoover dam.
If it were my truck, I'd have the XER273 custom ground on a 112+2 instead of a 114+2.

what does the +2 mean adds 2 degrees more advance in the timing i guess

More than likely the LQ4 will be cheaper.
It means the intake lobes are ground 2 degrees ahead of the exhaust lobes. By bringing the lobe separation angle and intake center line down to 112/110 instead of 114/112, you will help increase the cylinder pressure and low end torque of the XER273.
yeah i def plan on running only 93 or better
