The LS1 and LS6 can interchange with very minor changes (coolant lines and egr). I believe there are issues with the throttle cables when you put an ls2 intake on an ls1 motor, and I'm not sure about the LS7. I know as far as flow is concerned it's: ls1 < ls2 < ls6

LS1 intakes suck. LS6 intakes are ok. BBK intakes are ok. Fast 78MM intakes are good but the price is hard to justify. Fast 90/fast 92 intakes rock but require a bigger throttlebody and are expensive.
LS7 intakes rule but are NOT usable on the stock cubed LS1. In order to use a LS7 intake you need a 4XX shortblock and some LS7 heads.
For a stock internal LS1 the best intake IMO is a ported LS6. For big cams or heads/cam cars a ported fast 92 with a matching ported TB is definately the way to go.
