Thanks dude, it runs very well now, nice and smooth... Also reliable which is the whole idea. I'm not trying to get all crazy here, I'm happy with what it makes right now, I just want a *little* more without sacrificing reliability.

Why small cams? More cam is always better. Can you not rev high enough with the LS crank to take advantage of Skunk S2's? All you should need for the fuel system is a decent (not Walbro) pump and a set of cheap DSM injectors, right?
You can usually find those for near-free and send them to this local guy, fuel system done: http://www.witchhunter.com/

Skunk2 is about as beefy as I can go without rebuilding the whole valvetrain. AGAIN, lol.
edit: and yea, some people will be all "Don't be a pussy you can rev it higher than 8, you can get bigger cams, blah blah blah..." But I don't want my shit to blow up again so I'm taking it easy. 185-190 would be plenty for me with an NA setup.

Nate, there is a lot of technical information about valvesprings out there on a forum writeup that I will try to dig it up and post it. The engineering speak boils down to this: A really stiff valvespring is only necessary with a high lift AND high engine speed application, and a medium stiffness valvespring is fine on either a high lift/medium engine speed app or non-aggressive cam with high engine speed. So your 9000-rpm safe ITR springs should be fine with higher lift and duration like the BCIII's or S2S2.
Not enough fuel pump is a bad situation. Especially because at different temperatures and voltages your pump will max out at a different pressure/flow level, so the 'plateaued' area of your fuel map where you start really opening up the inject flow in msec, will have huge variances in running lean to rich or vice-versa. If you open the injector pulsewidth up and AFR does not go richer, time to back off. Easily lose an engine that way.

B18C1 GSR rods+crank w/ PCT's PR3 head BuddyClub springs/retainers Toda C's Custom fab craptech intake ITR IM/72mm TB/ITR header/test pipe/T1R mid pipe/ITR axle back RC 310's/Walbro 255lph pump Tuned on Power FC. Not to be confused with that piggyback shit. Making 172/131, need to replace my foam filter with a K&N, need a better header, and use my T1R axle back if I want to be in the 190 range. I wasnt making any power past 8k lol. BCIII+'s idle fine (Toda's idle fine too with the right amount of vacuum.) Car would start to pick up after 3000 rpms. I was averaging 25 mpg street+highway, and around 29 on the highway.
Interesting. I made 191 with ITR cam's on a c5 block with PCT's. Stock injectors (91% duty cycle) and stock pump.
