Get the cam on the base circle (valve completly closed) run the poly lock nut down until you have 0 lash then thun the nut 1/2 turn and lock the polylock down with the center allen head screw.

You have to use the same style lifers designed for the cam. If it's a flat tappet leave it alone. If you have Hyd rollers the factory lifters are nomally good for a long time. If you are doing a cam swap on a Hyd roller and you have a lot of miles new lifters are a good idea. I've seen the factory units go a long time

port got it right, make sure your on the base of the lobe and while slowly turning the nut rotate the pushrod with your fingers once you feel resistance your at zero lash. now just crank the nut another 1/2 turn but no more than 3/4turn and lock er down.

I've been doing this all my life and been fooled by a header leak. It can sound identical
