Dodgeparts.com So I am not getting new castings? Any chance of problems?I figured that I would be getting loaded heads.

Greg most current # is RL021608DE list price is $515 core value is $150. They are on national back order. There are 162 in transit from the supplier as of 04/04/13.

The $590 also includes the added core charge, which I will have to pay.
My one concern; are the new part numbers bare castings, with valves, or fully loaded with everything?

Heres a question do they put out reman part for all the core they replace due to waranty issues. Lets face it with the price of labour it cheaper to replace an entire engine instead of finding out what went wrong.
So the get a bunch of core engines, figure out what they can salvage and put it out as a Reman part # until exhausted.
If this is true then new heads shouln'd be coming down the line?

I checked out all the info given here, thanks for the info guys. The last word is, over $1200 for a new set of eagles now if you have no cores. What a bummer. So back to plan A, get my cores checked when I get home and see what it will cost to have them done up for what I need.

I gave up with the R&D on Eagle heads. The stock intake air speed was too slow from the git go from a lazy intake port.

Talk with Travis and see what he'd charge you to weld up your 5.7 quench pads. I tig'd mine up myself and had Travis milled them down to make them a closed chambered head. With my simple hand port job and using 2.08"int/1.62"exh valves my port velocity was 345 fps vs 300 fps when using an Eagle head.

Here's an example of a ported 5.7 head with 2.05"/1.57" valves vs a ported 6.1 head with 2.08"/1.60" valves. Even though the ported 6.1 heads flowed higher #s on the bench, the dyno and track times proved different. Just saying

Thanks for the info

with you but would there be a benefit for the other G3 heads. I would assume as the CID increases, more air being pulled through the port, the bigger heads would work more efficiently.
It would be nice to know at what CID the eagle head would come into play.
I'm thinking anything over 430 cid.

Once again Thanks Jerry for all your help. Matt

Sorry guy's. That was the dyno sheet when testing the 5.7, 6.1 and XV intakes. Here's the ported 5.7 heads vs ported 6.1 heads spread sheet.
