Factory 4-bolt Chrome BB Valve Covers

Did Chrysler make factory 4-bolt hole chrome valve covers for big blocks? Thanks.

Yes, I have a pair, unsure if they were parts dept or come on a vehicle.

Thanks, I thought maybe the 426 Street Wedge was 63-64-65, but I believe it is only 64-65.. in which case it be 5-bolt

Don't we have 4 bolt and 6 bolt?

I've seen exactly one set that I was sure were factory and they were on a pilot car engine. It was a 413 mocked up to look like a 64 426 Street Wedge in a 64 Fury pilot car.

1962 and 1963 M.W heads had 4 bolt valve covers but my 1963 415 HP and several other 4 bolt valve covers I've seen had the extra material around the lower end corners like the 1964 and later valve covers had but no holes in them
None of the OEM M.W. valve covers had wire looms on the passenger sides due to no room between the valve covers and the intake manifold, the baffles in them where higher also to clear the adjustable ductile iron rocker amrs
The first set of stock chrome valve covers I saw was on a 1965 426 street wedge motor

Yes, lol, 4 and 6.. not sure why I said 5..

The set I have do not have wire looms on them or the extra corner material like Cab said. I wonder if someone just had a set of MW chromed, or two 4-bolt LH ones chromed?? They definitely are original covers one way or another..

Likely cuz small blocks only have 5 (I got your back!).
