I have pressed tin plates under my rocker pedestals to channel the oil away from the valve springs. To quote from 'Ford Y-Block' by Eickman,

"Valve spring oil baffles were installed under the rocker arm shaft supports until May of 1956. A service letter at that time advised that they were no longer needed due to changes in the rocker arm lubrication system".

What changes were made, do i need them, and do i need to be concerned at how much will it change rocker arm geometry if i remove them?

Tia, Al.
