Hot Rods Buick Valve covers

I have a 401 Buick V8 engine with cast custom valve covers and want to return the engine to stock appearance , what year steel stock valve covers fit this engine , thanks Mike b

 

Any 364,401,425. 1957-1966

 

Thankyou thats great

 

I would opt for the later years as they have provisions for a PCV valve. My 57 and 61 364 vents via the valley pan with a draft tube, and my 64 401 has a PCV valve in the right valve cover.

 

you do know, that some came stock with cast covers
