They are a bad deal at any price. Edelbrock Victor Jr is the same price as what it would cost to make them as good.

I believe the “P515” numbers are the Edelbrock made stock type head.
I’ve done a few set of these....... they’re pretty nice heads IMO. Way nicer than the MP stuff they replaced.
Maybe if MP stops selling them, Edelbrock will start marketing them as an “RPM” head.
I like the Victors, but I don’t think it’s the best choice for all hemi applications.

I'm not sure which part number my aluminum MP hemi heads are, but they've served me well. They were new sometime around 2004-2005. The guides are soft, but other than that I've had no problems w/ them. Been running them since 2006.
The casting on mine is 2531110-M

Because of the price on the Edelbrocks, (and the flow) they made every other head obsolete for performance applications. The head you are talking about would be fine to put on a stock Street Hemi cruiser.

Rick, just what is so bad about them? Are the castings poorly done, or is it the quality of the hardware? It sounds like if you got a set for free, you would use them for trot line weights. LOL What is the story? There is nothing wrong with the heads in a stock power application. I've had them and used them. The problem (for a performance based application) is the price of the Edelbrocks. $2,600 (or whatever they are today). If somebody gives you a new set of the heads in question, you will have to UPS them somewhere, have them ported and larger intake valves installed to get to the 430 cfm that the Edelbrocks flow out of the box, and shipped back to you. Your bill will be close to $2,600. Now do you see the problem? Victor Jr's are a game changer.

My MP heads flow 430 cfm w/ the stock size valve. The Edelbrocks are a great head, especially for the money. I spent over a grand having MCH cnc port my MP heads. Wish they were available back when I built my hemi, but there weren't as many options back then.

If you want a stockish head (or say one for a 472) The Stage V's are better quality and look original to boot, they used to be around $2k a set bare, I haven't priced them lately.

Stage V heads are very nicely made pieces....... but...... the bare ones that have been sent to me are fairly labor intensive(unfinished guides and seats) and if you want to get something back that’s “ready to bolt on”, you’ll have several hundred $$ in parts on top of the labor.
For the hot street, street/strip type build using smaller bores and less than 500 cubes, I like the Ede made MP heads.
Mancini shows assemblies at $1485/ea.

P4876 is (was) Cummins. 110-M casting number. They machined 'em. Have fun, read between the lines and Come to your own conclusions, I guess The superseded P515 is Edelbrock. 110-M1 and I believe M2 (showing a little Mopar humor) casting number. Supersessions usually happen for a good reason.... The head were talking about is one of the items MP management (of the 2008 timeframe) replaced based 100% on customer input. Same managers who did the world block, the aluminum 452 wedge Head, the wedge branded rpm intake, and alot of other very worthwhile projects. Some effort went into it. I guarantee more would have happened for the good, had the same staff stayed on. Is P515 NS1? If it isn't, then I'm not sure what to make of "when they're gone they're gone" (unless referring back to the p4876 stuff)

I thought there was some seat falling out issues with the early ones?? Sent the set I had in and had new seats installed, made them a little pricier. Jim

Well, thank you. Been out since 2013 but this stuff is in my blood. I'd consider going back under perfect circumstances (probably never happen).
There are many great running vehicles out there with Cummins machined heads. Chip's car comes to mind! So they are not at all horrible products, but it's smart to have Them checked and gone through.
The p515 are just more user friendly, like most Edelbrock products. I really have to hand it to them.
They only have to hire and empower one or two qualified folks who cares, and are pissed off and driven enough to force the changes needed. I know someone who....I'm fairly confident....could fix the whole block supply issue in probably less than a year.

Speaking of blocks, does anybody have some prints or CAD files? I have the front and rear bolt pattern drawings from the Chrysler books and various other little things, but does anybody have a file that I can use to machine a block from a billet?

Well one can only hope.
Trans, from your discussion with D*****, it would seem You might be talking about quality and engineering related problems with 2006 era water blocks, Wheras I was attempting to talk about supply chain/purchasing and procurement issues with 2008-up Dalton/World/formerly Royal oak boring (most recent NB Fowlerville) Siamese products.
In the case of the more current Siamese piece, it's a matter of getting people paid and kicked off. the engineering related items were mostly ironed out. Compared to the water block, it might Be low hanging fruit.....easier to deal with. That's the one I was referring to...
Truth be told, demand is high for both products...they're missing the boat....
I like D*****, However I have to remember when communicating with him he always considered The World block to be vastly inferior, and something of a joke because of the amount of engineering input from outside sources. As you can imagine, I have opinions on that but will keep em to Myself.
