The making of a cylinder head

live right down the road from you in Goldsboro. When you get ready to build a header I might be able to help you out. Here is a picture of the header I built for my T modified.

 

at 25 i am of the last generation to know what you just said.


ever think the kid was just stupid for the shits and giggles?

 

I have a question:

Where do you find head gaskets for the OHV conversion you are doing? Making my own heads is on my short list of things to do. Mine will be cast aluminum...

 

I agree!

 

I didn't take it as he was being a dick, I think he just missed the point. No need to get angry about it, life's too short.

With that said, yes, I'm interested too. Keep the pics coming.

 

Kris: Ifyou can build a cyl head you should be able to build a head gasket. For years pepole have built head gaskets mostly using copper as a material although brass & alum also work.

 

First off, kick ass of you to take on the project, even better to share the process.

Second, anyone who questions the why, does not quite grasp hot rodding.

 

That's kinda what I was thinking. Just make one out of copper...

 

Here is one place to get a head gasket:

Copper head gaskets are traditional, and easy to make.

Or Cometic will do it for you.

 

Started the intake ports to day cc the heads. It is about 9-1 compression a little more than I want. The intake ports are a little hard because I have push rods and head bolts in the way, plus it is a long way through the head to the valves.

 

When you free hand on a mill you use both hands, and move the table two ways at the same time.

 

Now dammit George, your cheating. Show us the set ups. Just seeing the result teaches me nothing.

How many guys were building heads from scratch 60 years ago? 10,20,a hundred? How many guys 60 years ago just bolted on parts? that would be be many and many as in 90 percent belly button Flathead Ford V-8's. A guy back then who built a GMC or Chevy 6 was different to say the least.
And what did the Model T engine builders think when the V-8 was introduced in 1932? "No one will build engines anymore since you can buy a super powerful engine right from the factory"
There's home made stuff being built today but a lot of it isn't what you would consider traditional so it's not seen by people into old hot rods.
That's got nothing to do with this topic and I'm still watching.

 

Great post George, love to see the work progress, and someone doing it hisself.................

 

This is why they invented SBC's. Only crazy people do stuff like this. Keep up the excellent work.

 

Now dammit George, your cheating. Show us the set ups. Just seeing the result teaches me nothing.

Sorry but there really is nothing to see. Just bolt the head to the table, or angle plates and go to work. I used drill bits, end mills. Different sizes some with a hand ground radius on the end. Then just free hand the big radius.
There is a picture of the piece on the mill table some where on here.

 

wow to cool making a head , gotta love this site for cool projects

 

George, the pattern making that I used to do, some people would call sculpture. I'm reminded of a quote from Michelangelo (I'm paraphrasing here) "I carve away everything that isn't my sculpture." You are freehand sculpting on a 2 axis plane, as I see it. I'd like to try some of that, one of these days. I once watched an engine block being carved out on a 5 axis CNC, don't think that I'm ready to freehand that though. Keep it up, this is cool!

 

**subscribed!** i greatly respect your ambition and talent. well done.

 

This is it tell next week. Putting in the exhaust ports.

 

Awesome...
Hard to beat making your own parts from scratch.

Especially complicated ones.

 

Most impressive.

 

Those look like some pretty long tunnels that you are carving. I had no idea that you were raising the ports so high. How big is the chunk of metal you are starting with?

 

Yes the Intake runners are long, the head is 8" wide. The reason they are high is to get a better line to the cylinders.
That is the bottom half of the head, now the top half next.

Material is 2 pcs of 2 1/2 x8x20

 

can we have another tech week just so you can win!?

Had to smile at that. Been there.

Thanks for showing this. Very interesting.

WOO HOO!
I was watching this hoping the ports would be raised as steeply as possible. I'd love to see the exhaust head pipes come out of the head @ 45 degrees above horizontal!

 

Subscribed. This is looks like it will be awesome!

 

George-

Been machining for 53 years, but that mill is unfamiliar. Not often X axis ways extend beyond table, except on a jig bore. Make?
