what are the benefits of having ls6 heads on an ls1 motor? can you feel the difference? and is it worth the money to swap them out?

Here's my LS1TECH educated guess:
LS6 heads with .040 Cometic head gasket to bump compression and better quench will add maybe "20hp". Figure in 8.7/1 DCR (slight seat of the pants power difference)
FAST 90mm intake will add "10hp", MAMO ported 90Mmm FAST will add "20hp". (slight seat of the pants power difference)
Just for instance, if your LS1 car is making 360hp with a 224/228 cam and headers, you should be making atleast 400hp with both of the above mods. (40 hp is a good power difference).
100hp Nitrous System is very noticable and cheaper also.
