I have a older 5.3 with ls9 gasket's eBay studs run around 20lbs of boost from a s480 I'm swaying to a 05 lm7 my question is should I just throw my valve springs and push rods cam and intake on the lm7 the way it ia or should I swap it to ls9 head gaskets and eBay studs too

I would do new LS9 gaskets for sure and I don't think the studs will work on the newer 05 motor. The pre 04 blocks use the 4 short studs and the post 04 blocks are all long studs.
