I am going to be the guy who talks about what folks did before there were any fancy speed parts.

Take two sets of valve covers, cut the first pair say 2" from the flange, cut the second pair 1" from the flange, then weld or braze the top from the
second pair on to the first pair, and presto.

Note I wouldn't actually do this...I would just get something else and wouldn't sweat whether it has a stock appearance quite so much.

I have no logo Indy covers on rpm heads, with comp pro magnum rockers, no clearance issues.
