Cold Valve Setting
First, you won't FIND an official cold setting unless the engine was originally specified that way. There's an "industry" accepted fudge factor as 70AAR said. If this is NOT a factory cam, you need to go by whatever the cam is, by whoever ground it. If it's not on the paperwork, you need to contact them.
Either use the Mopar "fudge chart"..................
or use the EOIC method. What this means is.....
EXHAUST OPENING, ------------INTAKE CLOSING
What you do is you bump the engine until the EXHAUST on the cylinder you want to adjust just starts to OPEN, and you set that intake lash
Then you rotate until the INTAKE has opened and is nearly CLOSED and you set that exhaust lash
WHY THIS IS GOOD. Because unlike the Mopar chart, which is ONLY good for that firing order on a V8, EOIC works for ANY pushrod engine, whether a Briggs single or anything else you might run into "in between."
