Little bit of a rant about Mopar heads...

Alright, check this out:

My car has a 5.9 magnum in it with Iron Ram heads. Why does it have Iron Ram heads? Because both of the heads on this 86K mile motor were cracked between the seats. Solution, just plan on buying aftermarket heads if you're running a Magnum engine.

OK, so then I've got two stock eliminator projects I've been developing. They may end up just being motors I drag to the dyno as a proof of concept kind of thing. Working on a 74 360 and a 71 318 combination.

So, I've been trying to get a pair of 308 heads, and a pair of 302 heads. I've been combing the scrapyards for engines, poring through Craigslist, etc.

I have 12 308 heads. ELEVEN of them are cracked between the seats, most of them on every cylinder. The highlight here is that one motor only had about 80K on it, and one of the heads was clearly a reman unit. It was cracked also.

I merely have 6 of the 302 heads, but have not found a single good one yet. Just bought a pair out of Colorado off of Ebay, but the guy refunded my money because when checking them before shipment found that they were cracked too!

It would be a real kick in the nads to spend Stock money on a pair of heads just to have them crack. its seriously making me rethink this foolish idea.

I think Ma Mopar gets a big frigging FAIL on the induction hardening already. I can't believe they actually got all the way to the current hemi engine before putting in hardened valve seats LIKE EVERYONE ELSE has been doing for years.

For the record, on the Ford side I have bought and sold at least 20 pairs of the GT-40P heads off of the late model Explorers. Not ONE of them was cracked. Not a single one!

The only useful bit of info here is that I would recommend nobody ever pay shipping on a pair of these Mopar heads that haven't been thoroughly magnafluxed.
