Push Rod Tube help needed

[TheRookie]

Hi Guys

I have a set of 1.25 Empi ratio rockers ,the ones with the adjustment screw on the Push rod end. The rocker shaft on these are offset at the bolt holes so they sit slightly lower .

Can I get away with stock tubes once geometry is done or is racing tubes recommended

Thanks

I don’t know about those rockers personally but if it were me, I’d use the wide mouth tubes to stay on the safe side. Last thing I’d want to have to do is change them later.

I’m not familiar with those rocker shafts, but I ran similar 1.25 rockers on Scat solid rocker shafts for a little while (measured around 1.2 IIRC), and the pushrods showed signs of rubbing the Scat pushrod tubes I was running at the time.

I upgraded to CB pushrod tubes, and didn’t see any more rubbing on the pushrods.
