The cam card for the M4F I put in my 261 5 years ago says .014 on the intake and .016 on the exhaust.I degreed the cam 4 degrees advanvced as recommended on the cam card.A few degrees of cam timing change will move the power band of the engine up or down a few hundred rpm no big deal.
What stock valve lash settings are you talking about, .006 and .016?
