were all chrome notched valve cover sets 1 large and 1 small notch

 

Yes, The short one is for the driver side to clear the brake booster and the long notch is for the passenger side to clear the A/C housing. Even if you did not have A/C or power brakes this is what came on the big block Cutlass and 442.

 

I second that answer.

 

The 1967 big block cars used only one notched cover, on the driver's side, to clear the new-for-67 larger brake booster. The A-body redesign for the 1968 model year brought a different A/C box design, which required a notched cover on the passenger side also. These covers are all the same for these years, though I believe only the H/Os got chrome.

 

Thanks Joe! Just learned something new today.

 

I believe the '67 W30 had chrome covers, too, along with the later H/O

 

my '68 H/O did not have chrome covers.

1969s did.

 

yes the 68's were painted red.... and i know this has probably been posted before but its one of my favorites to watch

 

Interesting how they have the breather lid flipped , lol

 

Thanks for reply I have a pair that was given to me in 80s by owner of a 67 442 and both are small notch so was wondering
