This post shows the Roller Rockers and the valve cover revisions made to provide clearance for the rockers inside the valve cover after the B3 spacers were installed.
These rockers were purchased from Jim Cox probably five years ago. They are new never ran, have pressurized oiling to the roller tip and the adjuster end.
The B3 spacers moved the rocker shaft up a bit over .200 I checked the clearance with molding clay, rolling the engine over by hand. The outboard adjusters hit the valve cover hard. The adjusters below the valve cover internal baffels just touched the baffels. This is with a valve cover gasket installed in the valve cover.

To provide a safety margin I repeated the clearance test with the valve cover gasket removed and the valve cover bolted in place and made modifications for clearance.
Photos below show the Roller Rockers, the valve cover modifications, and a side by side comparison of a stock valve cover and the modified valve cover.
I applied Loctite 290 to the welds. Loctite 290 is a wicking fluid intended for sealing porosity in welds and metals.
The cylinder head I am using is a 1987 Hydraulic Head and valve cover.
