About a year ago or so I asked John about Rockout Inserts for Twin Cam using Vulcan billet rocker arm supports. He asked me for some dimensions on the rocker supports, and then made me a set. I'm just now getting that motor together, a 124 inch. They slid in really easy and smooth, and when I installed the Vulcan rocker supports on the head, there is zero play anywhere. I'm sure this will make the top end tap non existent.

Thanks John

JEEZUS.... Rocker porn lol!

That's great to hear brother, thanks for working with me on this.

Looking forward to seeing more about your build 

John @ Rockout

Thank you John, not many companies will make a part for an application they have not supplied in the past. As I mentioned above, they slid home with ease, but then at the end they pressed in snug.

Just a followup. After having ridden the bike, the valve train does not have the Twin Cam tick tick that many of them have. The Rockout inserts do make a difference.

Looks real nice !
By curiosity, do you know the size of the drain holes ?

They're 0.125", because I drilled them that size.

Okay thx
I Wonder why they make them smaller (as do oem)
