Lookin to replace my Proform rocker arms? One already broke and there pretty weak. Just curious if 1.65 ratio rocker arms will fit under the stock valve covers (centerbolt). Here is the link of the Cat ones I'm considering:

I think what you need to worry about is rubbing the pushrod slots. Put em on and let us know . BTW, how did they break? thats kinda scary.

 

I am pretty sure that the poly locks are too high for the stock valve covers. Also, I think you are going to have interferance issues with the oil baffeling in the stock covers.

 

Not sure how the rocker broke......due to not exactly sure when it happened. One day on my way home from work.....it started running like crap (Wasn't even beating on it). After troubleshooting, came acrossed it. Later after researching......come to find out Proform's are known for this and pretty much suck.

Thanks for the replies!
