Default 2003 5.7 Hemi

Well, I just got with the valve spring failure disease that seems to plague the Hemi engines . mine has 44k on it.
Getting a new short block and 1(yes 1) head under the 7/70 warranty.

1) has anyone had a similar spring failure, resulting in valve pieces trashing the cylinder etc.?
2)has dodge come up with a RELIABLE solution to the failing "beehive" shaped springs?
3) what are your thoughts on only 1 replacement head (more than likely re-manufactured and therefor milled flat -.005 to -.020"?

The dealer tells me that Hemi heads cannot be milled down, first head I've ever heard of like this(I think he's full of it). And that the compression difference side to side won't happen!!
What are your thoughts on that??

I'm suddenly feeling like my life long love affair with Mopar may be on the rocks!

I just hit 87K on mine, no problems yet except trying to change out spark plugs; wish I'd looked into that before getting a hemi. As for milling; that sounds like a blow-off to me.

I have heard that the 6.1 head (come bare) can be built and fit the 5.7 for less than you can get the 5.7 heads for complete.

Is there a benefit to doing this? other than $ saving?

there isn't enough meat on the bottom of the head, to machine it down.

i got 2 complete spare cylinder heads, with aftermarket valve springs, pushrods, and spring retainers.

So your saying that the dealer isn't blowing smoke with that statement.............?

What can you tell me about the springs? Are the replacements going to fail in short order too?
