1.5 or 1.6 ratio how to choose?

The stock speedmaster Springs have plenty of clearance for what you are doing and plenty of clearance for the push rods with 1.6 to 1 rockers or at least I do...
But always check...
After that DON'T OVER THINK IT...
People get so caught up in all the guru comments..
They end up spending too much money on things they don't need...
