So here is an updated PROPOSED mod list:

1998 LS1
10.25:1 compression
milled, P&P LS1 heads
underdrive pulley
NNBS intake (I will buy a cable 90mm TB)
2800 stall converter
tr220 cam w/ 114 LSA
heat sinked 6.0L coils (proven wheel horsepower over LS1 coils)
probably go with some steeper gears, as I am sure what gear I am running right now
longtube conversion headers, true dual exhaust with an H

What year does the NNBS intakes start? Any chance you could provide me to a link on one?

Also, just to ensure I would order the correct cam, any chance of a link on the tr220 114lsa cam?

Should I go with ARP rod bolts? I know they are the weak link inside the engine. When we changed cranks in my brother's LQ4 he went with the ARP rod bolts since he was around 450hp on the engine. I think since I am rebuilding the engine to new, it would probably be good insurance.
all of that seems good to me...stick with single exhaust though. true dual moves the power band up. im running single exhaust and shifting 7k
