Early 71 LT-1 Valve Covers

[Steve Beech]

The engine in my 71 LT-1 is apart right now, and I have been photographing all the components to have a record of the numbers. The car was an early build of about Sept 01 1970.
I have a question about the valve covers. Both left and right have the following numbers cast inside.

P-3932417-LH C-1 CBC
P-3965543-LH
P-3965544-RH

Are these the correct valve covers?

Thanks much---Steve

Yes, I believe they are. I think that very early 1971 may have used the twist-on style oil filler. If so, these are correct. Later used the push-in style and one of these would not be correct for that application.

Thank you Joe. Yes the oil fill on this car is the twist on type.

Back when I was 1970-72 team leader, I recall judging some early 1971s with twist in oil fill cap -- both aluminum and steel rocker covers. I am confident they were using existing supplies of rocker covers for very early 1971.
