Looks great Brian and the flow numbers are awesome. Mopar Magnums or aftermarket?

Looks good, what does the air speed sound like on the flow bench?, just right, slow, fast, coarse, manometer staying steady, think you know what I mean
Port is very stead up to .600 and then is a bit up and down, not horrible though. Port is pretty smooth actually, very balanced port design
At .700 lift it's not too bad either...just at .630 to .680 it's a bit rough. I can't shape the short turn any better due to water close by.
I'm putting a set on a 392 short block soon with 13:1 and a solid roller so we'll see what she does

Just as the eddy heads are not a full on race head, neither are these! I'll have all the info you guys want tomorrow nite. I'm off today and going to enjoy my family. No matter what they cost, they will always be cheaper than ANY other aluminum head out there and they will hold their own...I hope we shall see. Cost as always will be much cheaper than anything else out there making similar power with better components!!

I too am very curious on the price point and how long these take to machine. Brian, What machine are you using? Also-Will this program fit into an EQ casting? J.Rob

Intake MCA is 2.200 at the pinch.
Intake port poured right at 200cc.
