    You mentioned he got them from Alabama, I read into that as being he probably gets them from Alabama Cylinder Heads (ACH).

    I put a pair of these on my rebuild a few years ago, they appeared to be good quality but am not sure where they are actually cast. I put 40k on them towing and had no issues. I sold the truck though but am sure they are doing fine.

    John, did you ever get an answer to your question? The pair of heads I got from ACH weren't too great, one had alot of core shift. Unfortunately they needed to go back on one of my service trucks, now after 10k miles I water in the cylinder. To me it doesn't matter about warrantee, its the down time. Are there any heads that are not made in China?

    I've decided that none other than new AMG castings will do. I ended up finding some heads in my collection that could be used.

    Next set will just be new AMG heads.

    Sorry to hear of bad heads on your engine, that's been my fear, and you're not the only one.

    That is what I bought for the engine I'm building. Paid about $900 for the pair. Genuine AMG with non magnetic diamond precups.

    hey john, try 6.5liter.com, this guy gets his blocks from brazil, and i think his heads come from canada, also my brother jim just said he gets one of his blocks from canada as well... jim talked to him on the phone one time, over there they love the 6.5l...

    you might know this guy better than us......

    Sorry for the hi-jack...use some caution with 6.5litre.com...for the only reason being that if you ask to visit his machining area, you will get a flat out.... no.

    Not saying he is a bad business, however I thought this was a little distressing... he does his machining in the same city I work in, and refused to divulge the address. Reason-it had to do with taxes??

    Just wanted to see the quality of these Brazilian castings before I plunked down for a motor.

    Good Day!
