Cobra Jet AR Heads

Hello, I was wondering if someone could educate me on the AR Cobra Jet aluminum heads? They are on an engine that is for sale locally and I have a decent base knowledge of the new SCJ heads, but not the AR heads and don’t want to get into something that will cause me trouble.

Here is the info from the listing
"Big block Ford 460 stroked to 557 $6500.00 obo. Has Probe forged pistons , Comp Cams XE284h , ARP head and main studs , ARP rod bolts , Eagle rods , Scat cast steel crank , Cobra Jet AR aluminum heads with new valve train . Compression will be around 10.5-1 and pump gas friendly. Also has new front sump Melling high volume oil pump with Ford truck oil pan. "

Any input and advice is greatly appreciated. Does this seem like a decent deal?
Thank You

I think those were the first Aluminum heads to come out that were based on the CJ iron head.

Later Mark.

AR stand for Alan Root. I think it's the first alum CJ head.

That's my thoughts as well . The original aluminium CJ's were basically a copy of the cast iron CJ's. Still a good head but not in the league of the newer SCJ + P-51's

A truck pan is a rear sump and requires a rear sump oil pump and pick up

Thanks everyone for the input. The engine seems like it is priced too high. In the photo, it has not pushrods, rockers, or intake either. Thoughts?

THAT depends upon the year of the truck, LOL.

That definitely is NOT to high a price for that engine as is "IF" it is put together right and is not yet worn out and needs to be refreshed; especially if NEW valve train stuff comes with it but separate.

I agree w/Randy on price and make sure that a experienced mech that knows what to look for checks it out. Pull valve covers and peak at valve geometry,check pan,and at least 1 rod bearing and take a look. Those heads are a good head and can make some good power. It doesn't take long to put $6500 in one. Some times acc.'s will add up to a lot more than that.

If he doesn't want you to check it out. Walk fast. jmo

I should have posted this in my original.  I just talked to the guy and it only comes with what is pictured.  From some research I have done, I can get a comparable short block for 3k plus shipping from Cars by Carl, and I am not sure the value of the heads.  Maybe I am missing something, but it seem more like a $4500 package at best?

The A429 heads are decent, but need some work to get them to to the 380+ cfm levels.
All depends on intended application.
These heads (worked by the right person) can certainly reach or exceed the 800 hp level.

It is difficult to see if the heads have been ported looking at the pictures.
Porting a set could add additional $$$.

That being said $6500.00 does seem a bit over priced. A carb to pan deal might be ok at $6500.00
But not for long block only.

My opinion of course.
