'98 LS1 cam....

carb'ed ...performer intake...will be msd EFI -5

those heads probably dropped your compression a little, but the cam should make more power than the stock cam. 330ish would be my guess. long tube headers would pick up some power

They make 305-325ish, so assume 350-360 pretty easily.
