GMPP cnc ported heads with hollow stems for $1400 range and some new rockers best IMO, check all pushrods. New lifter baskets, new head gaskets and new TTY bolts...and after all that the extra 100$ for pushrods and $ for better springs as the ones on the new heads are not even able to do stock lift are insurance, just as many use bushing rockers.
And check all the lifters, for $100 again.... and while your at it look for the ls3 chain dampener to be shot.... Just some things I would do.
