No Rich, that isn't correct. In fact, we were allowed the top plate to tie the sides together, and the port mods-splitting the siamese ports- if we wished. We did the top plate, but time and money prevented the splitting of the ports, although we may look at that later.

We are also allowed to go to a 5 main crank, from the stock 3 main, if we wish. Again, time and money have hampered that effort, at least for now.

What we were not allowed to do, was make an adapter plate, to bolt OHV heads on- that is only allowed in the 4 banger class.

I knew you had the top plate. I thought that a welded bulkhead was your first thought and that was nixed. I am guessing you could run the OHV heads if you are under 325 cid?

No, I never asked about the welded bulkhead.

We can run the OHV under 325, IF we use the original head bolt locations- no sort of an adapter.

I submitted a plan for a 3 piece head, with the chambers as part of the bottom adaptor piece, but that didn't fly either. Upon reflection, I have to agree that it crossed the defined lines of the rules.

But you get creativity points! :-D

That's a new one on me. No adapters. I guess you can't just drill into the deck? I'm pretty sure we can raise the ports if we want to. Just not in Production. But we wouldn't have an engine swap. Quick change or a nonstock supercharger. Or any supercharger. So I don't think it's a legal Mod. Pickup either. I'll work all this out when I get the RFTA rule book printed.

Haha!

I do have a Frankland Champ QC sitting here, if it would help.....

Next phase

Head with patches machined flat, Rich did this during the last two weeks



Rich also machined three pieces of angle iron flat on every side, one for each exhaust port.



Here is a picture with all three in place



The head is bolted to angle plates on the mill so the adapters can be mounted with machine screws



Picking the spots to locate the holes for the screws



First hole drilled, tapped and countersunk



Second hole drilled, tapped. Starting on third mounting hole which turned out to be too close to where we planned to weld the port onto the angle iron. Mistake! Good thing this is a test



Me, working on the center adapter



All screws drilled tapped and installed, preparing to drill large holes for ports



Large drill centered in exhaust port before drilling rough hole into adapter plate



Drilling rough hole in adapter, now it has to be ground out and shaped



Locating the head bolt holes, then we would reinstall the adapter and drill the hole for the head bolt. These were done one at a time.



Head bolt holes all drilled



Test ports, Rich is going to make the flange this week, or next. Thanksgiving is coming, we don’t plan to work next weekend.



From the side

Zenon wanted to do this after I told him about doing some Cleveland heads using the kit they used to sell for that. I showed him a Pontiac head that I had cut for the same modifycation. Pontiac and Oldsmobile engines are crying for raised exhaust ports. It sure couldn't hurt the Stude either and maybe lots of other engines would benefit from straightening out the exhaust flow. This is an experiment to see if JB weld will hold. I think it will. But brazing or welding will work for sure. And welding cast isn't the nightmare I thought it was. We also butchered the intake side. Two ports for Jack Vines to try his idea with and two for Zenon's curiosity. The head was already broken when Jack gave it to us for this.

Very cool!

Are you going to be posting the intake ideas and work?

And I'm a bit curious as to the face of the head.  I know this is just a prototype, but what can you do for valve sizes and shape?

Yeah, this falls into the "very cool" category.

All I wanted to do was try this to see if WB weld would work, and just to do it. Since doing the Ford heads I have wondered why more heads don't get this mod and why doing it with angle and tube wouldn't be as good as the aluminum pieces that came in the Ford kit. Zenon wanted to do the Stude head, which would never have occurred to me. But I now believe it is a good head for this. Jack and Zenon had different ideas about the intake side, so #1 & 3 got Jacks idea and #5 &7 got Zenon's. I personally hope nobody ever sees those ports unless Jack is right. At any rate the head is pretty much done now for what it was supposed to be and no more milling is planned.

Hmmm, if you're not going to post the intake side, on this thread, will you at least show them to me when I stop by? :-D
