This is the first completed head. Now to try it out. Looking for feedback.

Nice Joe, its amazing the individual talents on this forum.

Looks like the plugs set into a deep well, extra cooling capacity?

Water outlet machined through the flat portion in the front with a special casting needed?

Looks like lots of squish area, dome top pistons or standard?

Any idea of valve size?

Split intakes or individual?

No V notch from the plug area to the combustion area?

Paul,
There is 2 inches of water cooling,The water inlet has to be figured out yet since the height of the head, like fronty's and rajo's, the combustion chamber is for standard pistons but there is enough iron on top to machine out for high domes,The valves would be what ever you can install with the standard head gasket,but you can go any lift cam since it does not taper in till the top, I was after a little higher compression and that is why I chose not to make the V notch.

These look like the combustion chamber that Kevin Prus has already developed in Aluminum in the 26/27 style. Kevins heads will be available in Chickasha in 3 Weeks at Booth NG08headsheadsheads

This one is cast in iron.

Morris,
Why don't you let Joe have his fun? You tried to hijack his last thread on his project too:

Joe, they look great!

Love these heads and the cast iron is cool. What production numbers are you thinking of.

Joe, are they standard 1/2 inch plugs?

i'd never use an aluminum head if a cast iron one was available. looks great joe, and american made, i'll bet !!

Joe,
I've been wondering how you were coming along on that project. It looks really good. I look forward to reports on the performance. I also prefer not using aluminum.
I know, I know, most modern cars have a mix of iron, aluminum and other materials. Pressurized systems, running temps and modern coolants make a difference. Plus, we expect to put 150K miles on it in eight years, dump it on someone that will drive it into the ground and junk it before electrolysis can deprive us of the last 10K miles.
I hope to get 50K miles on my T and still be driving it with minimal maintenance in 25 years.

Joe, Thanks for the update!
Drive carefully, and enjoy, W2

In my motorcycle racing days there was one guy I could not beat. He was a motorcycle mechanic.

I traded labor with him before he would show me what the HP difference was. It was two cycle so might not apply to four cycle.

Inside the piston webbing several holes were drilled that simply atomized the gas air mixture much better.

Vintage carburetors have terrible atomization.

What I am wondering is if a deflector or deflectors were placed in the right area in the combustion chamber swirling or directing the fuel air mixture and taking up space for more compression would be a benefit.

I seen a 427 Ford factory racing head, just inside the intake valve a venturi was cut like a venturi on a carburetor.

Paul,

You would have to be very careful here not to introduce an obstruction that would cause the the fuel vapor to gather and condense back into droplets.

Joe,

Looks very nice. Do you intend to add the small "steam holes" to the head?

Will the back end of the head clear a stock firewall?

Looks great Joe!

Seth said the same thing to me Jerry, on a two cycle after the fuel air mixture leaves the crank case it moves through transfer ports probably 3 or 4 inches before combustion. It did not make a difference in the HP gained.

Way to much testing and experimenting for an idea. Its just a thought!

It looks really good. You know of course that I would like one, although probably I will want to "customize" the combustion chamber. It would be for my Bonneyville project.

Joe, Henry Ford never did anything that was not required to be done.

Note that Kevin kept the top shape of the water return path.

Your head is rather flat, which must considerable reduce the amount of cooling water available in the head.

For the guys that are making the aluminum heads you have no worry with me, I plan on making a dozen and half of them are spoken for already with the wheeling and dealing that goes with T's.
Jerry three of the steam holes are there and it will not fit a stock firewall, it is the same height as rajo's.
I did not intend on mass producing these when I started, I like the iron heads and they are getting pricey, so me being a frugil person decided to make my own.
Les, I will get one poured that has plenty of iron on top of the combustion chamber, fill in the core box 1/2 should do it.
I have 1 and 11 to go!
I am going to send one to Chickasha with The Coil Doctor for him to play show and tell and let Mike Bender play with it to see how it does?
Joe

Joe what kind of $$ for this good looking head

I just finished some heads out of gray iron, they worked out better than the malleable iron at my day job. There was a couple guys that had an interest in a ruff casting to machine the combustion chamber as they wanted, get a hold of me off line to tell me what you want.
