Depends of what you want. Flow is one thing, crossectional area is another. If you have cubes and you want power, you'll need a proper port size. The CNC 440source head is very good for a big high torq engine, but the port size will hold it back at higher rpm.

Is everything in the stock location with the Eddies?
~thanks
Yes.
FWIW I had zero problems with my source heads out of the box and I've been daily driving them. Plus the CNC'd source heads are done by modern cylinder head so they do get looked over again before you get them.

Did Edelbrock change the sparkplug angles back to stock angles at one time?
I thought only the Mopar Performance heads made by Edelbrock had at least the sparkplugs at 90 degrees to the head again.

I ran the numbers for the ported Source heads on desktop dyno and they made more torque and HP than ez1 heads. This was with a mild solid roller and with the 512 and 528 configuration. However, they are at their limit at that point so if you want more power in the future then you have to go with a different head.
For what you're doing I'd go with the 512 and the ported Source heads. They don't need any special rockers, etc.
Thanks for your effort! the 512 is about where I am hovering, anything more and the RR will be on skates.....
