The cam in my Savoy now is a Howards solid flat tappet is still running fine. It's fairly aggressive 620/612 256@50. I used Howards EDM lifters and Gibbs break in oil with inner springs removed and followed Howards break in procedure. Almost 2 years and only set the lash once since the install and that was just for maintenance inspection.
I wouldn't buy another Comp cam with all the other options out there twocents
