Zippers makes great tapered push rods Fueling sells the same tapered push rods also

 

If your pushrods are rubbing there will be a tell tale sign on them about mid way. FWIW, neither the S+S or smith's i have had in my motor with the 9b rubbed.

Travel limiters may not help any noise either but can create their own.
Lots of places in the rocker boxes to check and measure though!
Also, certain oils will help or hurt. Got an oil pressure spring or shim in there?

 

I have a tw-68 678 lift no rubbing

 

I am running a 650 lift with zippers tapers with no problem

 

Thanks for the replies about the pushrods,now on to my sumping issue.If you call 9oz.sumping and not nothing.

 

At 9 oz, I would not loose sleep over that.

Should I use the travel limiters on the "B" lifters or leave them alone?It's been a long winter so far and have nothing but time to get ready for the warmer weather.My engine will see a lot of high RPM duty.Obviously don't want to add noise to the valve train if I don't have to.I only have about 125 miles on break in so far and haven't put it through the paces yet.Just would like to address the areas needed now and spend more time riding than wrenching when it comes time to have fun.Initially seemed to clack between 2500 to about 3800 while using straight 50wt.
I read where the short duration on high lift Wood cams and installed travel limiters created more noise.Anyone have the same results?
