Xflow Head for US Swap - Any Interest

[rocklord]

I was on one of the Australia forums and someone on there just sold a crossflow head to someone in the US who wanted to do a head swap onto a US engine. This has been done by Mike1157 on a US250 and discussed here: ci/XFheadswap.html

I was looking around the attic of my garage and realized that I have more crossflow heads than I'll be able to do anything with.
Along with the head, I have some new cams from stock EFI to high performance, head and valve cover gaskets, steel or alloy valve cover, a stock 2bbl intake, an EFI banana intake, and a stock cast iron exhaust manifold. Basically everything you would need to slap one of these heads on a modified US block. The head will have to be cleaned and a valve job performed along with the head modifications.

So, I was wondering if anybody would be interested in purchasing one of these heads?

If there is any interest, we can discuss what setup you want and price.

Just to let you know, a $50 Crossflow head bought on eBay Australia can cost $150-$200 in shipping.

Are they old crossflow heads or barra crossflow heads? I do not know much about them but I thought the older heads bolted straight up to our engines. I am not too much on the modification of the block but I am interested in a direct bolt on head.

[rocklord]

The only Australian head that is a direct bolt-on is the 250 2v.
You can read about it here: ci/OZ250-2v.html

The Crossflow engine replaced the 250 2V in 1976. It is a crossflow design that uses canted valves similar to the V8 Cleveland head. The Crossflow head is wider that the 250 2V and US head, so modifications to the block is required. See here: ci/XFheadswap.html

The Barra is a DOHC engine. This head cannot be used on a US engine due to the fact that the cams run off the crank with a long chain and modifying a US block would be a PITA.

So if you want a direct bolt-on head, go with a Australian 250 2V (good luck finding), or an aluminum head from vintage inlines when they
become available again.

Sorry I am not too informed on the aussie heads. Thanks for the info. Are the heads you have a good swap for performance?

[rocklord]

If you read about the xflow head swap at ci/XFheadswap.html , MustangSix stated
"We estimate that our "mild" 200 with 9.0:1 CR and a stock cam will put out 155 - 165 hp. Hotter versions will easily exceed 200 hp."

Those are pretty good numbers.

HI Rocklord, I might be interested in one of your heads and parts depending on the cost you have in mind it would need to be fairly compleate package though. I have also been hunting for a car in the low budget range for a coupe of years in the Az. area to do a perforance build up. Unfortunately I lost all my engine parts and car collection when I moved to Az. so basically am starting from scratch again.

You kinda threw out there a scenario of a $50 dollar head costing $150-$200 to ship like that was going to be more expensive than one of your heads, so how much for one?

Yes I'm very interested in a cross flow head. I want to toss it in my 200ci.

I'd also like to know how much a crossflow would cost. My block is about to be rebuilt and if i can get a cross flow head i might get set it up for that...

Thanks!

Installing a OZ Crossflow head onto a USA non-Crossflow block requires extensive block modification. You may want to find the Crossflow head to non-Crossflow block threads here and read through them thoroughly before you decide to purchase one.
