Depends what you want.

I put kits together myself either using my own cams or any of the known BD range.

You have several options for various kits starting with re-ground cams only using std springs, right up to my high spec ground from blank's complete with 380lb double race valve springs and new followers. You also have the choice of solids or hydraulics so the list is extensive. If you require more info email me direct, otherwise if you know what you want from piper just call them direct.
