With any luck all of my talk on here won't cause my cam to flatten on startup. I've had good luck with Clay Smith lifters on the handful of flat tappet engines I've built.

Each was different. Let's just say I've learned and paid dearly because of it. lol
BUT prob won't be messing with a heavy valve flat tappet motor the rest of my lifetime. To me, it makes no since to try when the materials and manufacturing we are getting are just not what they use to be.
