@rocky posted:One question I have is whether the cam for a straight “roller” valve train is (can be) the same as the cam for a “hydraulic roller”.
Assume with a straight roller cam, you have to set the valve lash occasionally?

What is a straight roller cam? Do you mean a solid lifter roller cam?
It is recommended that the valve lash be "checked" and adjusted if necessary on any solid lifter cam periodically v. a hydraulic lifter that is self adjusting.
