1.5/ 1.6/ 1.7 ratio rockers

So is there a down side to using higher ratio rockers? Why bother with the stock ratio then, everyone should put the highest ratio rockers in they can as long as their is enough piston to valve clearance and when your rebuilding an engine that shouldn't be a problem.

Depending on the heads most you don't need crazy lifts. Also needs more spring pressure and can make the ramps to fast to control are the few I can think of.
