Do I need guide plates on cobra roller rockers?

[CARYEMLER]

Just got some 93 cobra roller rockers do I need guide plate or shims?

Guide plates, no. Shims, maybe. You'll have to install them and check.

I didnt use either on mine. Had em on for 8 years

I shimmed mine, but no on the guideplates.

What cylinder head?

I dont have any guides or shims on mine, but I have some valve train noise. I need to sand the base and tighten up the tolerances a little....
