Raised port Stude heads

[zenndog]

Thanks Scott, I have an engine with rockers and rocker shaft. This started off as what seemed like a simple experiment....I didn't want to start taking apart the motor, but I probably should have removed a set of the rockers from one head.

Soon I will see what the results are and then the next step will be decided.

  I swear I am not trying to hyjack this thread, but I thought some of you might be interested in looking at a set of raised port Early Olds heads done by Jocko Johnson in the early 60's.
  I have them listed for sale on Ebay under the parts and accesory heading.
  Punch in Gasser, and then Racing Parts and you should find them.
  I included a little history about the heads which at the time were "State Of The Art".   Bob

Cool piece of history, Bob!

Thanks Bob, anyway we can figure out what the material was that he used to build up and replace the port roofs with?

[zenndog]

My guess is brazing.

[Peter Jack]

It's brass. Brazing gets that colour once it's been sand blasted or glass beaded. Bob also mentioned something about furnace brazing in his description. I imagine what actually happened was the head was preheated in a furnace and then torch brazed. It would then be buried in sand or insulation so it cooled very slowly.

I was looking at one of the stock heads I have this morning.

Here are some pics









Here is a little reinforcement I did this morning









That spot is only epoxy for about a 1/4". I did't want it to blow out during flow testing. On a head built to run on an engine that would have been welded. The port feels very strong though.

Ports are as far as I am going to take them for this experiment. The head has been shipped off to a Stude enthusiast to be flow tested. Boy has this taken a while. Will update when info gets back to me.

This is such a "interesting" endevor-- really looking forward the the results!!!!

[tauruck]

Golly, that's a lot of work. I thought my Cleveland hiport mod was a job but this is wicked. I really hope it works out for you man. I added this just for comparison.

[zenndog]

Tauruck-That looks interesting, you should start a thread.

I am not shure how the port will work, but it will be interesting to see.

[Milwaukee Midget]

What I really admire about this experiment is that this is applied intuition, research and development brought to bear on an otherwise orphaned design.

This is the no-man's land where breakthroughs can still occur without a bankroll, and simply for the thrill of the project.

I look forward to seeing the numbers this head produces, and I thank you both for bringing us along for the ride.

Thanks to Tom Covington from the Studebaker Racing site for doing the flow test

Whooee  if Tom is excited  I am excited and I am not a Studiepile This just shows hot rodding at its finest    to Rich and Zendog
