Or if you're taking about increasing overlap with the same cams, you'd retard the exhaust and advance the intake cam.

Jac Cammeister Ryann you're right again duration not timing. The toe of the cam is passing the rocker at exactly the same time regardless of valve lash setting. Can you imagine designing the profile of a camshaft AND setting-up the machinery to grind it accurately. My God given brain is too small. I'll settle for adjusting valve clearances.
