[Identity Crisis]

Does anyone know where I could find the answer to my question about the studs?

Which roller rockers are you referring to?

I am using the Comp Cams 1.6:1 Roller Tips. So do I need to source out the Iron Head Studs for this to work on my 3.1 Heads?

So, these ones? http://www.60degreev6.com/store/inde...d&productId=33

From the Product Description...

They were designed for the iron head setup, which you can use their rocker studs to get an adjustable rocker arm setup. Or, you can do what I did and reuse your stock nut on the stock stud and just torque it down. Stock pushrods worked for me just fine. You should check your pushrod guides as a reliable source has told me that the groove needs to be ground down some to fix new geometry. Otherwise you risk breaking a pushrod or your guide, neither of which is good.

Yup those be them.

Here is where I got the idea that maybe I was missing something.
