Got an email from him several weeks ago regarding something else, but no update on the crossflow head from him.

Progress as promised. Some pics of the new head. Remember, this is a raw casting, no machine work is done to it yet. It is also the first one made. Many refinements need to be done to get good consistent castings. Next will be making a jig / jigs for machining. What do you think? Intake ports are the round ones and are on drivers side. Sparkplugs are also on driverside. Exhaust ports are on passenger side and allow for multiple bolt patterns. You might also note the kidney shaped combustion chambers. Should be a fun one to turbo with the intake and exhaust being seperate. ![](http://imageshack.us/scaled/thumb/17/sparkertrialcasting001.jpg) ![](http://imageshack.us/scaled/thumb/266/sparkertrialcasting002.jpg) ![](http://imageshack.us/scaled/thumb/837/sparkertrialcasting005.jpg) ![](http://imageshack.us/scaled/thumb/560/sparkertrialcasting004.jpg) ![](http://imageshack.us/scaled/thumb/7/sparkertrialcasting003.jpg)

Looks darned good for as cast, even better for being the first one out of the tooling.

That looks good. What is the chamber size? What valves will it use? What rockers?

Beater, I am not sure on the chamber size. 1.94/ 1.6 valves. Standard pedestal mount Chevy 6 rocker arms.

Round ports are much easier to deal with when making headers & intake manifolds. Square ports are a pain to make runners for. This guys paid big bucks to have runners made for his intake ports. post #111 & newer. http://www.theturboforums.com/threads/353498-Aussie-t51r-feed-202ci-holden-6/page5 $1800 for just the runners.

That is very interesting. My first impressions:
I like the shape of the combustion chambers - it reflects current thinking and should burn fast and not need a (large) piston dome.
I like the placement of the exhaust runners but don't think round is necessarily the best shape.
I wonder why the intake port opening is so low on the casting. It looks like there is real estate to move it upward and minimize the effects of a tight short side floor radius. (see my photo above)
It also looks like you have the option to make the valve train either stud-mount rockers or shaft-mount rockers. I like that insofar as I have become a convert to the benefits of shaft-mount.
Symmetrically opposite paired cylinders can be problematic.
I realize you are quite far along in the casting process. I'm just brainstorming some thoughts which no doubt you have addressed. Good luck with this project.

Frenchtown, I had to think about your answers/ questions a bit.
You are looking at the ports wrong. The intakes are round and the exhaust are rectangular.

Hey Tom, You're right - I did think the round ports were exhausts and the rectangular were intakes. The rectangular ones just looked so much larger than the round ones so I assumed they were the intakes. It looks like a fun project.

If these are produced and can be had for somewhere around the $1,800 range then I will definitely be interested in having one.

I think life just got in the way. I talked to him a few months ago about something unrelated and the head was never mentioned. This has been an ongoing project for close to 4 years or so, and sometimes you just hit a wall or lose interest.

The cross flow head is still work in progress and is more a hobby than commercial, hence my priorities are to my family and business (try manufacturing competing against China). I have seen things on the first casting that have required a rethink as to ease of casting etc. During the last month an intake pattern has been done for triple side drafts that could take any log style manifold bolted on as well.There is a cast exhaust pattern almost finished,three into one style. Here in New Zealand there are not so many foundries to choose from capable of casting a head but saying that I like a challenge! Alistair

I know it's been almost a year since the last post, but I figured this thread (more specifically, this product) deserves a bump. I'd love to see these go on sale, and might even be able to buy one on top of that.

I would be interested in this head being in Australia. As for Ford Australia made an Alloy Cross flow headed 250 from 81 to 93 . And CHI make an Alloy head for the Chrysler 265 Hemi.

I think he ran out of ambition. Not the case. The first casting was cut up and examined. Realizing there were areas that need more work. The pattern was changed and then the second casting was poured. This casting was also cut up for examination. A third has been cast and is getting prepared for machining. This is expensive to do. The pattern work, casting cost all add up. The machining costs will also add up. Be patient, the project is moving forward.

There are lots of folks around who talk about 12 port cross flow head production that seem to run out of something. "Ambition" is as good of a word as any. ![grin grin](/ubbthreads/images/graemlins/default/grin.gif)

Thanks for the update Tom! I am going to file this away for long term. Hopefully our truck will be ready for it by the time y'all start selling it.

That is one Ugly looking head. But main Question is What does it flow? How big are the valves and How big of a valve will it take? Also that rear Pipe Looks vary close to the starter So I can see a heat issue there.

The second distributer is a tall one. Another special part? The first headers would fix that.

I bet the timing would be fun to set on that one with the headers hot.

I bet the timing would be fun to set on that one with the headers hot. Not to mention the routing of the plug wires... I can understand why they went with the exhaust on that side but it does pose a few challenges. On the other side would have been tough for any kick-down linkages or throttle cable routing. Kinda damned if you do sort of thing. That said a turbo set-up with this would be really nice!

Here's a simple solution to the distributor: a right angle drive using two Boston HLK101Y bevel gears. Now ANY distributor (or mag) could be used. Works for mine. ![](http://img.photobucket.com/albums/v608/6racer/adv23t086-2.jpg) Also note the intake manifold adapter - it allows for the use of ANY aftermarket or production intake by changing the stud locations to stock production dimensions.
