Hello everybody.
I would like to know the differences between a 041 Plus and a 044 head...
They seems to be look a like.
I just know that los banditos, los panchitos and 041 heads are almost the same...
Tanhks and sorry about my poor english.

The port design is totally different and the heads are a much heavier casting on the 044. I have both 041 and 044s as well as a new set of wedgeport 044s. You could never think of porting 041s like the 044s, WAY more material everywhere to work with.

Hummmm... I understand.
But the 041 Plus have some difference between a regular 041? It have more material, or just big valves?
I do have a set of 044 ultra mag port but didn't get them installed in engine... I will built a engine that will not need so much porting, so I am looking for a head that provide me more cooling than the 044.
In fact, all these Auto-Linea's heads are made very very near from home (about 25 kilometers)... But I have to buy at USA (there I pay less than half price when compared to Brasil!!!!!)...
Tanks!

The 044s have very good cooling, a similar amount and style of fins as a stock head. I know we both live in very different climates but I have yet to see cylinder head temps of over 350*C after an hour of cruising around town in my buggy with a 2332. I think with a propperly done cooling system you won't have any problems
I do not have any experience with the 041plus cylinder heads so cannot speak about them. Perhaps someone else does.

| you could also look at the mofoco heads made in usa.I have both 044's and mofoco 042's both wedge ports. I have about 40000 on the 044's and about 70000 miles on the mofoco heads. I have burnt my self on the headers but not the heads..but both sets are ceramic coated in the chambers&valves & exports. do they run hot??? I used a cheeo ir temp gun on the ex port and it said 197 on the outer square flat portion of the 044's thats all i had to check with, |

041's use 14mm spark plugs. The 044's use those damn worthless 12mm spark plugs that are twice as hard to find and twice as expensive.

Good to know... What kind of spark plugs have the MOFOCO heads?
Are they better than CB heads or it is just a matter of option?
Thanks a lot.

In Brazil fortunately these spark plugs are very cheaper... We have a lot of motorcycles that uses that kind of spark plugs.
But thanks for the help.

My 044s with 44x37 dropped a seat in #4I after 18K miles. I am going on 45K on some 043s with mega heat and duty and no problems yet. I got the 044s on their way to one of the kings of cylinder heads for hopeful repairs.
044s do run a little warmer, but really it comes down to abuse. 400 degrees or more is gonna cause you some risk.. and anything less is probably ok on any head. |

I can buy them over the counter at the local parts supplier my shop deals with, not much more than a 14mm short thread VW plug. I'll pay a bit extra for plugs for a much stronger combustion chamber design. And if you start getting into bigger valves more material between the plug and seats is more than worth a couple of bucks a plug.

| slalombuggy let me ask you, did you have to do any work to those wedge ports before you bolted them on to get that great cooling. cuase i AM LOOKING AT A SET OF MINI WEDGEPORTS that I just got from cb that need some help. their is alot of excess casting material on them in the cooling webs (some are 3/4s blocked) and the machine work in the chambers is not the same between the two heads. I think I am going to have to put in some quality time with these puppies or they are gonna run hot. |

Its definately a good idea to clean out the casting slag out of the cooling fins, if the "ports" are blocked then your cooling will be affected

| Anyone have a source on the autolinea 041 plus heads. CB no longer shows them on their site. |

After blowing plugs out of their holes and stripping the threads with stock heads and stock HP I would much rather use a 12mm long-reach plug. It's much stronger, not going to blow out and allows less interference in the chamber.

| Look for the "EMPI 40x35 12mm spark plug" cylinder head. It is the same casting(Auto Linea). |

I know it's almost a year since the question ws asked, but yes, I did do some clean up work in the fins and around the outsides of the ports to get airflow through the head, only took about half an hour and a couple of drill bits......

Has anyone had any problems with these castings? I know they are autolinea castings with the empi logo on them but any feed back would be nice.
Thanks |
