How about these cams ??

Ironmike, I agree, checking Valve lash very simple and also a non issue but the last solid I I had was a flat tappet and the sound was noticeable, I've never had a solid roller, I wonder if there's a difference in sound between the two? But once again, if there's a considerable torque gain I'm all over it. I'll try the ol search and see if I can get some comparisons
