A 440 with iron heads, 500 hp, and very streetable; call Dvorack Racing in Waldo, Fl .We can't believe the engine he is building for us, visited twice, see it happening. Call Dan. Google his national records. Price good.
Are you aware Edelbrock's stuff is also outsourced? It is. He can claim his stuff is "made in USA" as long as a certain percentage of his products are made here.
Now I'm not so sure... I'm finding a lot of posts like this:

I know that's just a few folks opinions but the exposed gasket and dropping valve issues seem to be repeated on several forums.
So, back to the MP heads. Everyone claims the "452" head (5153524) is the same thing as the Edelbrock RPM (in fact made by Edelbrock w/ a Mopar logo) but w/ straight plugs.
What about the MP 4876311? I can't seem to find any feedback about it. I would think it's a better choice since it has a smaller, closed chamber. Do people not prefer the factory 906's over the 452's for the combustion chamber? Why is so much made of the "452" Edelbrock copy head but so little mentioned about the "906" 4876311 head?
I've got the vacuum outboard carbs and the only tunning I've done on them (besides idle mixture) is change the vacuum springs to get rid of the bog it had off then line. It runs good but I'm sure there's more there for someone that knows what they're doing. I've contemplated adding the Promax metering plates but wasn't sure if it was worth it or not.
I'm talking to Modern Cylinder Head about CNCing the MP heads. They have a program for the Eddy's and this is the same head.
