So I've got a Chinese cyl. head on my motor at the moment. It says QF on the front. The motor is not in the car yet. Should I get a rebuilt chrysler head on there or just use the chinese one?

How? What was wrong?Originally Posted by raccoon
it cracked after a few heat cycles, started to get compression into my overflow.
if you get a good one side by side and compare them yourself. there is no way you would still use that head. im not just being a big china hater here btw. but those heads are terrible.
do you know how many dead k cars I see at junkyards with bran new china heads. I would wager money when you see a new head on a old car at a bone yard that head put the car there.

Ya it looked pretty cheaply made as I was putting it together.
Get yourself one of the newer Mopar ones made in Mexico, and you will be much happier.

Does anybody have a side-by-side comparison? Just for poops and giggles.
There's an opinion I will definetly be listening to. Thanks Gary!
Purchased 4 new for evaluation and 2 were junk right out of the box!

Gotcha. I am going to be turning up the boost too, so I dont want any weak links like that.
Plus if you use a cast aluminum valve cover and don't grind down the inside right front corner you crack the valve cover.

Is the only way to tell if its a chinese head is the QF on the front?
The giant gay Chinese symbol on the front is a dead giveaway.

I take it the QF stands for "quite f*cked?"

A man has got to know his limitations.....
Any pictures of these china made cylinder heads ?
Even a mild port job will break through, been to the shop where a vendor from this site has their head work done,
Generated a BIG pile of scrap.

Hell, one of the ones I had was puking coolant out of the base of a cam tower.

I only seen pics posted on this site a few years ago 9try a search) and side by side.... the china head was horrible. Tons of casting flash..... and crappy amounts of core shift. Steer away! Looks like something you'd find at the Dollar Tree store

I have that same head you are talking about. Its actually what FM used as their CNC head. Its always been good on my last 2 cars. It holds over 500 all day with no problems. The only thing i ever had done was when the normal little cracks between the seats got deep i just had interlocking seats and bigger valves installed. I wouldnt think twice about using another one of these heads on a performance car. The only bad thing i have ever heard was that my machine shop guy told me it was a PITA to weld sometimes because it got a lot of sand still in the casting.
