LT-1 rocker and injector selection questions

I'm getting ready to put on LT-4 heads and a CC-305 or similar cam. My questions involve how many new parts I will have to get when I make the switch.

Will the GMPP hotcam roller rockers work with the CC305 or will I have to get new ones? Also, will I be pushing the stock injectors and need to upgrade to 28#? I'm already planning on upgrading the fuel pump.

Any input is appreciated.

Your rockers will be fine. You could use the stock rockers.

Select injectors by figuring out how much power you'll make. Sounds like some 30#s might be right for you, but do a search for the injector calculator, and go from there. Or, try www.racetronix.com . Jack at RT is super helpful, and really knows his stuff.
