Hey Cylinder heads guys- advice needed

To do the 11/32 valve thing right, you’ll have to redo the valve seats to ensure seat and guide concentricity.
I can’t imagine how 16 guides, 16 valves, and a valve job is going to be cheaper than new stands.
Not to mention, the stands might be fine as is with longer rockers.

The blue roller rockers?
Yeh, just verify the part number first.
I believe you’re looking for P4876345.

I also see there is a single for sale for $40.
Might be worth grabbing it as a way to get things measured up before buying a “set” of anything.
