how does this setup sound?
04 5.3 longblock
4L60e fbody
LS6 intake
00+ fbody exhaust manifolds and custom y pipe
fbody accessories + UD pulley + 01 harness and pcm
I want to use either an LS6 cam and springs combo, or ZZP 1.9 rockers. LS6 cam and yellow springs would probably run me about 250-300? ZZP rockers are 340 new and they claim 18 whp without changing springs:

I was also thinking of getting some used 243 heads. They would come with the yellow springs but would be 500+. Would these be pointless if I am not going to run headers?
TIA
