Heads

[66Sprint6]

I have head talk about different heads to go on the stang 6banger. Which is best, the Aussie 2v or the Argentinian??? There are 2 different Argentina ones arent there, well, which of all the choices will be the best buy if I want more power, fuel effecincy etc??? Thanx again for all the help guys,
Matt

Since the two guys that know most about the Argentine ME and SP are out partying this whole week - I'll give it a shot.

The ME was designed during Argentina's fuel crunch. It gives great low end power with a small weber carb and good MPG too. On the other hand the SP was designed for all out, triple carb big lumpy cam applications. I've been told the SP is best when your power range is between 2K to ???. These are just generalizations but when Southern Cross Racer gets back he'll give you the goods.

By the way check out 83fairmontI200's website, he has big huge photos of an ME.

I'm sure someone else will come along and give you more info. Me voy.

If I were to get a Argie head I would go with the ME because of the chambers. As for the Oz head I love it

As to which is better I do not think anyone on this site can really tell you. We still have people debating on a fully ported US log head and the OZ head.

Unless someone was to grab a US head, Argie SP, Argie ME and an OZ head and do the tests all on one car witout changing Anything but the head itself, no one will really know what is best. But this test would also not really tell the truth because you can not use the same carb on each head. You could maybe with adapters but one adpater that rasies the carb does make a difference.

Awesome, thanx guys, I hope to get more info about this debate, but it seems I am leaning towards the OZ heads. They look to be popular, and I like what I hear about them. Anyone have any reasons why i should go the other way, I have ALOT of time before I can even afford either, lol, so give it a shot!!!

whatever you decide, if you get the chance, you might want to jump on it as soon as possible, check here:
http://fordsix.com/forum/viewtopic.php?t=4850
but, as another head possibility, Jack has started working on a way to put a crossflow head on a US block (check the tech section for more info on the crossflow, and Jack's progress), basically, the crossflow is the aussie inline six version of the US 5.0 EFI V8, and it's something like 5% less HP than the 5.0 (225HP-5% = 210HP? that about right????)

just something else to think about...

one difference is that the argie head has a seperate 3 and 4 exhaust port and the other heads have a siamesed 3/4 port so you need to add a port divider. on the other hand you need to add argie headers, where as you can get clifford, hooker headers for us heads, and the pacemakers for the aussie heads (don't know if pacemakers fit the us head)
I don't know what the cost is for the argie head but my aussie head cost me 500 USD and so far i am very pleased.

check shop site to see what is available

i believe that the arg heads come with the stock cast tube headers exhaust

 

[66Sprint6]

I have clifford headers, will they work on the Aussie head??? I also have an exhaust port divider. About the cross flow, how much would that cost!?!?!?!?!?! By the time I get the money, it will prolly be out, but would there be any downsides to running that much power through my block. If not, Im all for it!!!!!! Would I have to change pistons etc. out??? Oh well, I am new to this awesome world of six cylinder build ups and love getting feedback from all you who know whats goin down!!

The argie and crossflow head both use specific headers so your Cliffy headers and port divider will not fit either one.

Clifford, Hooker, and the Pacemaker headers fit the US or OZ heads as both use the same style, as well as the port divider.

another pro for the ME is delivered with dual tube exhaust so you can sell your cliffy. Someone also has said that exhaust ports 3/4 are not siamesed so no more worries about the port divider breaking lose and clattering.

i don't know about the Aussie 2V heads running out completely, it will just get rarer and rarer till it won't be cost-effective to do the conversion
and as to the cost of the crossflow, well, as the tech section says, all of that is still in research and developement, but, when everything is finished with it's testing phase, i'm pretty sure full results will be posted about everything needed to do it, as well as the cost of it

hmmm, Mike, any plans to sell the XF heads, and possibly a conversion on the site once Jack gets done with his project and has the bugs worked out?

as to the strength of the blocks and how much power can be run through them, check this thread has a bunch of threads and links to follow, but to make it easy, i don't think we here have heard of an engine failing because of the block

good luck

I know someone who split a bore with a 60 over 221. That's the only one I've heard.

Looks like Im goin for the Aussie, I like the sound of the Argie not having to use a port divider, but due to the fact that I have already bought it all exhaust wise, and had never heard of doing such (head swaps that is) I will have to go with what I have. In the future maybe I will have more money to throw around and look into the different possibilities. I am still very interested in the crossflow design tho.
