Dont "need" them unless you are running a solid cam.

Most valvetrain upgrades don't really prove their worth until you get into high revs.  6000 and more.

Chryslers stock setup is very robust. On a good block, the stock setup will spin past 6 making power reliably. When the times comes, i prefer the comp steels. Usually sell just under 700 bucks. Dont skimp and buy cheap no names. You will regret it.

Proper push rod length is critical, it's why they make "cut to fit" push rods. Done right at assembly time, non solid lifter engines will self adjust for life. (While saving valve train moving mass/weight.)

What are "these".  There are a bunch of rocker arms for sale on eBay.  Most look like cheap junk. You get what you pay for.

If they are less than $500, don't buy them.
