Sometimes the cam was ground to use the smaller exhaust for the intake so the exhaust could use the larger intake valve to get out. I guess it was thought to be an improvement but I don't know.... 

That engine has intake and exhaust ports on the same side so probably still has larger intake valves. I don't know what they were trying to do since cross flow works better in most cases.

This was one of a few freak Pontiac engines Mickey Thompson experimented with? Both intake and exhaust on out board side of the heads. MT did all kinds of crazy stuff back in the early 60s. Those are without a doubt one off heads. I believe they still exist in a private collection.

At least I was in the right neighborhood, it was a GM engine I should have known.

I only remember GMC making V6 and V12s for their trucks but the V8s came from Pontiac or Oldsmobile. I did some research and found that they did build a 637 ci V8 for larger trucks and buses but it didn't look anything like that engine as it was the same design as their large V6 with 2 cylinders added.

They made a 700 ish cu in V12 that was 2 V6s together. 

 

 The exhaust side of the heads do look like Olds or Pontiac and the rockers, pure GM

I just edited my reply, they did make a 637ci V8 version of the V6 but that pic is not it.
