Does anyone know where I can purchase one of these for a NE engine that I don't need to roll into my equity line of credit? Or should I do a Pro-E model of what would be an ideal design and go and make a cope and drag and cast them myself....I've exhausted all efforts.....Thanks! :(
 
Hi bobco,

Here is the story.

I have a box full of special heads for the NE motor [I am sure the largest collection in America]. Almost all of them cost me over $200.00 each.

Because the NE motor can be modified to easily travel above 45 MPH, most don't need the better head.

Speed cost money, how fast do you want to go?

I remember as a teenager, that my '55 chevy would go really fast from all the modifications I did to the motor, but I also remember reaching a certain level, and to go a little faster cost a lot of money. This is also true with the NE motor, a small investment could take it to a certain level, but to go the extra mile costs a lot.

I doubt you will find a quality head for less than $200.00, because there isn't a large market, and the optional heads are all custom made in small quantities. I have tried many times to find someone to produce the head for under $100.00, but didn't succeed.

Everytime I have special heads made it must be in quanities of at least 3, and right now I don't know of 3 owners looking for them, and I sure don't need more in my collection.

If you want to try to cast your own, I will happily supply the needed information on combustion chamber design.

I have test heads with over 165 pounds of compression. I still have the first WC-1 head I had welded and re-worked to fit the NE motor [cheapest version of a performance head]. I have heads that were completely welded shut and a new pattern carved out, but the welding was less than stellar. I might possible let a few of them go, but would at least need my original cost to do so. I do not weld and had to pay local welders [ouch] to make the requested changes on each head. In my area if a welder even looks at anything aluminum the minimum charge was $65.00. As you can see speed costs.

If you want to contact me I will itemize my cost & supply pictures of any heads that would be of interest to you. Please understand that many were prototype heads and although work well, are what I consider "crude".

Have fun,

To keep up with the boys running at Portland, 45mph won't cut it. I need to be able to run 55-60mph. And there's one gent in particular who I'd like to out run.....more speed please.. :D

I sent you an email asking for your itemized cost and pics of the ones you'd part with....

How much for the 165lbs. one?

Thanks!

Wow

That head that you have is already one of Q's better works. I'll be waiting to see / hear the difference.
 
Hi bobco,

Just get out your checkbook! I will sell you one of my personal prototype heads [only 3 produced]. The intake valve pocket will need to be increased in size, and the head will need to be milled to arrive at the desired compression ratio. I will make it available to you at my cost, but I will warn you, it will exceed $225.00. If I were tying to compete with one of the OHV Whizzers, it is the head I would select, and used a very similar version when I competed with OHV motors over the last several years. All of the record setting flat head Whizzers use a very similar combustion chamber. Roger Brophy used a similar head design when he set the record at Bonneville. The super motor I am building for a friend will also sport this style head.
This style head added 30% more power when used on a vintage motor with larger valves. The combustion chamber was designed and tested by me to fit the NE motor, and only one is in the hands of another "speed freak" [on the west coast].

One additional comment you may find interesing, there were a small quanity of "decent" heads put on the last versions of the NE motor that can be re-worked to produce good power. In fact I just finished re-working one in my shop last night. I used this style head on my dirt drag Whizzer last year to compete in the "stock" appearing class.

Have fun,

I'll take it! You can email me the cost if you'd like and then I'll reply where to send. Thanks! :D
 
Quenton, I purchased a late '07 NE-5 bike. Any chance this model would have this other desirable head you mentioned? I guess I should pull the engine and see. Any possibility of getting a picture of this 'limited edition' head to compare to mine?
