Our motor build has literally been years in the works, so sorry for so many questions here.
So the motor we are building is 1970 440 with Stealth heads, Comp XE268H cam
This cam is pretty mild, so my question is about rocker arms.
My brother ran this same cam in his otherwise stock, smogger 440 with no problems whatsoever for several years. He did have the stock iron heads.
Now we are to the rocker arm stage, however the ones that we have laying around are too "loose" on the shafts to use. I hate to have new stealth heads and then top it off with old, worn stamped rockers.
OK....now my question. The shafts are great, no galling, pitting, etc. Are the mopar stamped rockers worth trusting in this situation?
If so, we will order the stamped rockers from summit (mancini stamped rockers are not currently available).
As you can expect, the engine is now coming together and the budget is almost gone, which is why we don't want to drop over $500 on rockers, but we want to do it right, too. (For those of you who follow, the money issue is also why we aren't pulling the trigger on EFI now also).
Anyway, sorry these posts are long, but I try to include as much information as possible so people know what is going on.
Thanks

The stock stamped rockers are loose on the shafts... just as long as the lower flat area rides nice on the shaft(thats where the load is at, not on the top of the shaft area)... the problem point on any old stock rockers are where the push rod rides... they do push through

As a rule of thumb, the stamped rockers do fine under .5" lift. I think they would do fine in your application.
thanks
are the restamps of the rockers from mopar a good piece? I can't remember if I heard something about them being thinner or something?
I may be wrong... ...................... READ the current Mopar Action for all info on stock rockers. Your comment about loose on shaft rockers tells me that you dont understand how stock RB rocker work and you OEM rockers are probally fine for that wimpy cam.
