No noi, Lifters will be new!!
Can they use the single valve springs from the piper or do these have to be replaced?
As I understand the des Hammil Book right, the pipers are not that much stronger than the original Rover ones.
Schumacher ( a guy like a tree from Germany ) told me, that´they run in a cam for 1/2 hour at 2500-3000 rpm with special run in ube.
Should be o.k.!
Thanx!!

Springs should be fine for the 3.9 cam.

Hope it runs well.
