Rocker Arm Part Numbers

[nitroxsteve]

I need to replace my rocker arm assemblies and NAPA shows two part numbers SEP R905 $16.49 and SEP R 905B $13.69 these are sealed power brand. Any idea what the difference is?

Sealed Power® p/n R905 crosses to OE Part Number J3242393. You can get them cheaper than what NAPA charges. Check Rock Auto.

 

Just curious: Why do you need to replace your rocker arm assemblies? Noisy?

I rebuilt the engine and found they are worn in the pivots very bad. I didnt have time to get new ones when I was assembling the engine so i just put the old ones back in and I'm just now getting time to replace them.
