Rocker arm step ups

those are the heavy duty non adjustable rockers...



Yep. The next step up.
Replacing a marginal part with a marginal part doesn't make a lot of sense to me.
If you want to upgrade and have a really tight budget , this is next.
If you are around 300 lbs. open , these are marginal.
Your cam and springs will decide what you want to put in there.
