Technical 1949 Cadillac 331 Valve covers

Early 1949 Cadillac's had two bolt valve covers and in searching I have struck out. Does anyone know who makes these or has a pair for sale. The bolt holes are centered and 14" C/L . They bolt into the rocker shaft end caps. Thanks.

 

Well, ya learn summick new ever day.

 

I never knew that and I thought I knew everything there was to know about the 331's.
I Googled photos of early 331's an there they were but still I don't know when they changed to 4 bolt covers.

 

I think 1949 331 was a one year only to have 2 bolt covers

 

Yup and there's even some aftermarket cast covers for em for lots of $$$$$ if you ever come across them.

 

Seein' is believin'...............

 

The two bolt valve covers were only used in the first 3 months of production. Also the red oil filter and wing nut type canister were also early production. But I think only the first month or two.

 

The other difference is they use a spring loaded plunger in the end of the cam,also only used for the first 3 or so months of production

 

Somebody told me those early 49s had floated wristpins.

 

Did you ever find a set? Because I’m pretty sure I have some
