lash with rotators.
 

When installing rotators (exhaust valves only) What lash (valve clearance) should I be using? The cam is a std.ford cam.

What engine...49-53 or sticking them into an earlier one?
Here are some tune-up specs.

I think maybe he's wondering what I was wondering last spring when I installed the later one piece guides and valves in a 59ab. Does one adjust valve lash as though it was a late model engine or use the specs required for the 59ab, which are smaller? The .019 seemed like an awful large gap to me so I went about 1/2 way between. Seems quiet enough, but not as quiet as I'm used to.

It depends on stemlenght and heat so a bit about how hard and hot you run the engine to...not only which engine.
Since most dont run their vehicles hauling rock its not a problem to keep it a bit tight.
