What you think a set of aftermarket valves will do for me?  
I have never considered changing mine before so I am looking for input…

uhm

Changing to bigger valves?

Swapping out OEM valves for OEM aftermarket replacements?

Bigger valves with a proper valve job will make a fair bit of power.

Swapping out stock valves for stock replacement valves will only make power if there’s something wrong with your old ones.

Head has to come off to do the work.

One of the advantages to aftermarket valves is that most of them will not crack like OEM rather bend when you detonate therefore minimizing damage.
