It don't look that bad to me either....at 140 K, my 5.3 was top end only. Pressure tested the heads, surfaced/grind? fresh springs (gm blue springs),ARP bolts/multi layer gaskets... stock cam shaft. I did not bother to run a comp test, or leak down on it....just read the plugs. None of the holes were pushin oil...other than a light bit of piston slap , on cold start, no issues> She pulls 45 psi pressure @ idle (hot)....damn fun to play with. Longhorn
