push rods, rocker arms, and pushrod guide plates

So it appears it the camera was playing tricks on our eyes. Both oil pans are the same size.

Next question. Are these the correct valve covers for a 63 qb block. For some reason I thought that they had a Chevy bow tie raised on them.

 

[Jim Sullivan]

Aftermarket or Canadian Pontiac?

 

[Jayz63]

Okay that makes sense. I did get the engine in Canada. Well looks like I’m needing to find the correct covers. Now.

The spark plug wire holders on both valve covers are also 1964 and 1965 -409 style (the type that uses push on rubber wire holders).
I also agree the missing raised bow tie does not make them original.

 

[Jayz63]

Awesome thanks for the input. Does anyone have any extra rocker arms and pivots they don’t want anymore. I’m missing two from my engine. Any any leads on some valve covers

 

[pvs409]

I sent you a message about 63 valve covers that I have.
I have some 409 rocker arms & balls -I will check what I have.

Original QA and QB rocker covers will have dripper fingers on the inside.

They also have a raised BowTie in the middle just below the raised strip down the center.

What is the purpose of the drippers. The blank chrome ones I have do the have the drippers inside. But I also have a nice set of offenhausers that don’t have any drippers.

The dripper's where to help oil the rocker arms as the higher HP engines had higher lift cam and heavier valve springs.

They actually drip oil on the rockers.

Chevrolet installed them on most engines that left the factory with solid lifters, they accumulate oil and it drips off the point onto the rocker arm near the valve stem. Only the HP 409’s had them, hold onto your wallet when you buy a pair as everyone is proud of them.

Jayz63 here are a couple of pictures showing the dripper fingers. They are a sheet metal stamping that is spot welded into the underside of the rocker cover. You can usually see the spot welds on the outside of the cover.

 

[Jayz63]

Yeah the chrome set I have without the bow ties have the drippers but I want to go with the original look.

 

[409gang]

Those covers in the pictures are factory covers off a 1963 400 hp QA motor

The higher pressures of the solid lifter valve springs put more pressure on the rockers and pivot balls and the manufacturers and aftermarket came up with various ways to improve the oiling there the drippers were a great idea,grooved rocker balls were another example.Chevy wasn't alone in using them from the factory,Ford and Pontiac used them also and there may have been others too.Pontiacs used a few different variations over the years.
