Do you need a special timing set when switching to a roller cam in a big block?

Looks like a decent piece for the money.

Torrington is best - a Good one ! Button for sure and stock cover ? Definitely reinforce inside and keep it @ a tight clearance I've seen where it rubbed a hole actually in a stock cover - do it right the 1st time

I appreciate the patience with me on this stuff.
I'm guessing that fore/aft movement of the cam has to be limited to keep the lifter wheels in proper contact.
I've never checked to see how close the timing chain is to the back side of the timing cover. The cover always slipped in place and I never thought about it.

Cam movement will put stress on the gear drive mesh - wear & tear , timing fluctuations

I bought a gear set for a roller cam (102-1004) from 440 source that does not have the Torrington bearing. Can you buy that separately and install or is the cam gear machined especially for the Bearing? I do have the cam button. Had no idea about the cover flex and good to know. Great thread!
