I have a 261 solid lifter cam that I'm installing. My question is do I adjust the lifters the standard .006 intake and .013 exhaust, or do I adjust them the heavy duty .010 intake and .020 exhaust? TIA

The adjustment spec is also the height of the "clearance ramp" built into the cam. so if you go with a different clearance, the transition from clearance to lift doesn't happen at the right time. That's also the reason not to use hydraulic lifters on a solid lift cam, as it increases the total duration by a bunch. Hydraulic cam clearance ramps are usually only .002" or so, instead of .015" or more.
