I just noticed that I forgot to mention the intake valve clearance. So, here are a few more bits of information:
Exhaust clearance (hot): .014"
Intake clearance (hot): .010"
For the intial setup (cold) clearances when you're assembling an engine, the TM says to use .010" on the intake valves and .015" on the exhaust, but I'd personally suggest using at least .011" for the initial intake clearance and .016" for the initial exhaust clearance, then tweak it when it's hot. (If this were an overhead valve engine, I'd add another one or two thousandths to those initial clearances, since there would be more and longer pieces of steel between the cam and the valve seats, all of which expand when hot.)
