cam
You would likely have to give more specific information.. is this an off the self cam or a custom grind ?.. what brand name is it ?.. type of cam lobe profile... etc..
120 degress is pertty large LSA.. but I'll defer to the engine/cam experts.. I can help you on swapping the LQ9 into something tho !
LQ9 has the flat top pistons
You didn't specify what head gaskets either ( compressed thickness?)
Also, as said before, that is a large lsa @ 120 sounds more like specs for a boost application, rather than N/A
just a example 68' Camaro 6.0L T56 w/ 4.10 rear gears
I am running a iron block 6.0L w/ LS2 rotating assembly (stock flat top pistons), LS3 heads. GM mls head gaskets .054"
custom grind spec'd cam: 226/234 .629”/.629” 113 LSA +2 advance
my pistons are fly cut on the intake side
Just because it may be a "good deal", doesn't mean that it will be "good" for your application
