6.1 Cam swap questions

USCG - So where can the problems occur? ( Remember this is a6.1 with no VVT)

My 5.7 cam swap went just as described with the lifters/retainers/pushrods.. I left the heads on, it was a simple job on mine at least..Joe

Joe - so what action do you take after the cam is installed to get the lifters to "drop"?
