Magnum-La hybrids VS EQ heads

so I'm currently building a 5.9 magnum that still has the LA oiling holes.

I was gonna just get EQ heads with new valves and a Hughes spring kit with locks and retainers, and a guide plate conversion with small block chevy rockers. but I came across a pair of LA Edelbrock heads part number 6077 for a roller cam that have only 5k on them for 860 shipped.
my question is besides shimming and new pushrods, maybe adjustable rockers, and new head bolts, what other things would I need to...
