The L92/ls3 heads require at least a 4" bore, ie, a 6.0 or larger to fit.

Nope, they're cathederal port also. Best bet would be the TBSS/NNBS intake swap for a GENIII 5.3

Sorry I was frustrated. I have an LS3 intake and TB, I have an 07+ truck WP, I know I need to trim the alt bracket, but it's hitting the WP if it's turned with the motor towards the passenger side, and the other way it hits the alt... So what am I missing???

hmm I dont know about the car tb but the one I saw that works is the 07+ truck throttle body. It looks like it doesnt stick out as far as the car one.
