Anodized heads are there now.
-
Thanks. The coupon code is 'BHQ'. Let me know if there are any problems.
-
Thanks. I will add the color options. I keep limited quantities of anodized heads but I think I can do inventory control on the new site.

Noss Machine has a new web site up that makes it easier to order domes and other stuff. Check it out and let me know what you think. There is a BHQ coupon code that gets you 10% off.
Coupon Code "BHQ"

Never heard of that brand. I might just be out of touch.

While it is certainly possible that something got out of here off by 0.002", that measurement is very difficult to take because it's an inside corner cut with a tool that has a radiused tip, although it is a small radius.

RadarRacing,
Where in the dome were they off by 0.002"? How did you check it?

Sorry I missed your calls....

I make domes for several builders. Sometimes they give me specs, drawings, or parameters. Sometimes they get my designs. I didn't make the domes in the pictures for anyone. Just wanted to clarify some of the stuff above.
-
It has been several years since my Super Cub domes were 'stepped'. I don't know if that head was designed for the earlier style domes.

I found a new plating shop to do the anodizing. I'll check tomorrow and see if I have a blue one on the shelf. Give me a call tomorrow after
about 9:00 central time if you want.

What domes and fuel?
-
use only the orings on the head installation. I answered this before the email, sorry. If you have any questions during
the install, call me
-David
-
Give me a call if you want and I'll try to help you sort it out. Some pictures of the domes might be helpful too.

There might be issues besides tuning causing the orings to blow but I might try backing the timing off (9 degrees is quite a bit of advance). The fact that it is
also blowing the plugs out points pretty strong at detonation. 'Shelf' domes are usually safe with alky domes but alky domes
aren't terribly safe with gas, (race or otherwise). The domes are 4mill 17cc? Did I make them?
-
timing also,
-
Could you be detonating? I ask mainly because of the 17cc domes? If you are detonating, something will give like the spark plugs backing out, blowing orings, or grenading the engine.....the first two are cheaper..
What is the kicking compression?
-
I make custom domes almost every day. The more info you have, the better. Bore, deck height, piston part number, etc.
Give me a call if you want at 918-358-3804

If you can get blank domes, and they aren't some really weird shape, I can cut the chambers for a very reasonable cost.
I don't 'modify' domes that have already been cut but if they are blanks, I might be able to help.

I hope I haven't been steering people wrong. I've told them my domes will work in the Chariot heads. Should I be telling them
something else?
-
Those domes are 30cc flat plate volume with a 0.110" step in the dome. When they are ordered by a builder, I sometimes just engrave something that will
identify them instead of all the specs.
-David
-
I can make some for you or you could get them through Jeff. If he ported your motor he would be a good choice. If not give me a call. It would be helpful to know what is in there now,,,probably 19cc stroker domes, maybe even 18cc judging by your compression.

I can't resist any longer....
A reworked stock head can perform very well. I use the term 'reworked' because simply milling the stock head only raises the compression and can yield a too tight squish clearance.
Brandon 'reworks' the head the right way as I understand. Nothing wrong with that.
-------------
Stating firm temperature, horsepower, or power curve numbers is impossible since there are so many variables. I could say "My xxcc xxmm bore xx degree domes with a xx wide squish area in a Banshee with xx carbs and xx jets and +xx timing will run 20 degrees cooler on a 95 degree day when the barometric pressure is 29.90. It might sound really intelligent to someone (probably not) but it would be BS.
The head I've been making for over ten years does cool the cylinders evenly and doesn't allow the coolant to just flow across the top of the domes. The combustion chambers need to be hot to function properly.
Bling, cooling, good and fairly unlimited chamber design, and ease of changing the chamber are the strong points of a billet head. It's not even limited to billet heads. There has been, and will be more, cast heads that use interchangeable domes. Stay tuned.

While quantities last, I am including a pair of 1" or 3/4" brake line clamps with head/dome combos.
This is whether the head and domes is ordered from me or a Noss dealer.
I am making less 'cosmetic' parts and clearing out some of my cosmetic parts inventory.
