I should have said " I remember those valve covers on your car Tom".

I have a set of 63 421 HOs on my 62 GP and the SDs on my 63 Lemans.The factory covers have a tab welded at the bottem of the tube to hold back some of the oil that gets kicked up by the rockers.The repops dont have that tab which causes them to slobber more IMO.Tom

Could use some wire mesh ( not as densely as in breather caps) in there to catch the oil and still pass crankcase vapors.
