Can the P$G Valve Gapping Instrument be used on Dove Rocker arms.



Thank you,

The ‘as supplied’ width of the Dove, Rocker Arm Specialists, and Harland Sharp aluminum bodied rockers prevents the P&G valve gapper from being used with the P&G “Y” barrel adapter.  Using a P&G barrel adapter for another engine might be an option as I’ve only got three different barrels for my particular gapper.

Thanks Ted

I think I can make this work with a #2 Barrel and X adapter, however I have to make some notches to clear the taper in the dove rocker and the dowel pin. I will photo the modification if measurements will allow this. It looks like not much has to be removed.

Why not just use a dial indicator on a stand? Thats what I've been doing for a starting point. just make sure the pin on the indicator is straight up and down in relation to the valve stem or push rod. Chuck in NH

Dial indicator on a magnetic base stand works great on a nailhead Buick because its a flat surface to locate on. The Y block head angle makes it difficult to register the indicator tip, it wants to slide up the rocker. The P&G set up fixes the unit to the valve spring retainer making accurate adjustments very precise.



If you can please show us a picture of your set up with dial indicator on a Y block head.
