Very exciting news! Three new cylinder head options
Hello everyone,
There is some exciting news in the Ford six world. Three NEW cylinder heads are in the prototype phase!
One will be an updated EFI chamber head. It will have a thicker deck, improved ports, and more resistant to cracking than the OEM version.
The second head will be the “Max flow U head”. It will be the same as the first, but will be CNC ported for better flow (around 200-250 cfm)
The grand finally will be an “all out” Aluminum Cross Flow Head! Estimated flow is around 350 CFM.
The master mind behind these efforts is a racing legend named Bruce Sizemore. The Max U flow head will be based off head he used in his “Preparation H” car.
Bruce is not doing this alone, there are many other racing legends and engineers contributing to this project. It is very much a group effort, as we all want this project to succeed!
My efforts in this project is to find people who are interested in one of these cylinder heads. WE NEED A HEAD COUNT! Without knowing how many people are interested, we won’t know how many to produce. This will be a LIMITED PRODUCTION!
I’d like to clarify that I WILL NOT be taking money. I just need names and contact information to forward to the rest of the team!

Ok I found that too more later.
Took me a while to find that and you had already posted it.

I wish this had been a year or two ago, as I recently finished building up a stock 300 head. (No way I can dump money on a head twice. 
)
After the enlarged valves and full porting job, the bench flow test showed 240cfm at 0.50" lift and 260cfm at 0.60" lift (the highest they measured).
I can't imagine what 350cfm would be like. Impressive!
What an extremely cool project though. Props for doing it.

Sorry for the lack of responses, I’ve been driving cross country. You bring up a valid point f250restorer. Bruce’s focus is on the product, not making a profitable company. Producing an aftermarket cross flow head for enthusiasts is an item on his bucket list. Quality is the number one goal.

Marmon V16..... I'd bet the typical owner of a Marmon V16 could pay for time travel back to the original sale date and buy a new head from the dealer:

The typical Ford 300 owner is checking the sofa cushions for gas money in many cases

I would be interested in knowing more, and possibly in for one of the heads. I've been reading the thread on Fordsix.com and trying to digest it all. FTF I know you post there also and have great input. My goal is mainly for a street application so don't know that the full cross flow would be that beneficial in my case, but also want to know manifold compatibility for the U head and cross flow. I'd think the cross flow would require specialized intake and exhaust but maybe the U head could use existing parts that are port matched. Does that sound right?
I have a complete 240 engine that I picked up cheap and had planned to harvest the head for some custom work and that may be a more practical way to do it. Still, excited about a 350 flow cfm head out of the box....

You are correct for the most part. The U flow head will use all of the standard parts and accessories. The cross flow head will need special manifolds, they are working on intake options.
Generally speaking... if you are looking to get more than 5,000rpm out of your 240/300, than the cross flow head is what you need.
