on those gears you'll want something like +1 Intake and +3 Exhaust or 0 Intake and +4 exhaust. Until you know what your V2V (valve to valve) clearances are, you'll want to maintain 4 degrees of seperation when adjusting those cam gears to their final settings.

In some cases yes, maybe most, it is what Skunk 2 says you should maintain. Unless you know exactly what your valve to valve clearance is, it isn't considered safe to use less than 4 degrees of seperation between your adjustments when tuning. I measured my clearances and go less seperation but others checked theirs and cannot. So it's not a one size fits all adjustment.
