valves clearance / 350

Good day,

I like to know if my valves are correctly adjusted or that I need to tuned-up.

What is the correct valve clearance for the intake and outlet valves by a cold engine?

Me and my mechanic are from Holland and having a hard time to find the correct sources.

I'm running a 350 block and as far as I know, except for my cammel humb heads, is everthing standard. Or at least I didn't discover any special (preformance)rockers.

Many thanks in advance!
