Cant find a lot of info online.
A local guy has some for sale.
They appear to be victor heads with a mopar logo.
Any pros/cons or experiences with these?
Thanks,

Those look like Max Wedge port Edelbrock Victors to me

After I had worked at mp for a few years,the Mopar version of the rpm head was launched and had proven itself, I was told there was marketing intent to do a similar program with victor heads. Initial Intent was detailed changes to make the heads slightly more user friendly in addition to more visible exterior Mopar Performance branding.

And so it came to be. However, this was a time some rather large fish were being fried by a tiny group of folks with not much for resources. Hemi and wedge blocks were all new, iron hemi heads got $$$$$$ production steel tooling, gen 3 was cooking, and basically many products were at a fever pitch during that time. The heads hit the catalog as "raised port aluminum heads". Wow. Such a high level of detail!

The next catalog came out, and this time they were called PIG PORT heads. Although we'd like our engines to make some bacon, pretty sure that was a typo. I couldn't take it anymore and appealed to the powers that be to change the name of the heads to Stage VII. I made a word document, sent a neutron bomb email and the whole bit. I felt my case was iron (or aluminum) clad, in that these heads fulfilled the promise of the stage VI. The intake spacer was cast in. Management liked the idea and ran with it.

So there you have the marketing story.

From an engineering standpoint, I know Chrysler engineers liked and approved the product but I dont think anything really changed other than the branding. I was told there was intent to fix pushrod and distributor clearance but I am not sure that ever occurred. at that time, bankruptcy had hit and you can imagine the affect on folks who worked there. They look about the same to me. Pics to follow.

So, for better or worse they are a Mopar Performance branded victor head. The branding looks cool in my opinion. I don't work there anymore so don't worry about hurting my feelings, if you think they're junk say so. Does not matter to me.

Is the branding worth extra? I'd say if you like the appearance of the Mopar wedge logos, and you can get them for about the same price as victors, or less, go for it. I'm going to get mine ported and will probably build a motor around them.

You're welcome--Glad to post something worthwhile for a change laugh

A 572 wedge crate engine had been discussed, and these were the heads for it.
I believe the detailed changes to the heads were to be outlined during development and
Change requests submitted to edelbrock at that time. The intended refinements, As far as I know, never occurred because the crate engine never happened.
Had that happened, It likely would have killed the 572 hemi on power and cost and may have forced Some difficult decisions.

I've considered writing a book about my time there lol

Not big on some of the magazines and books out there but I would buy this one if you ever decide to do one. Off topic but a friend just recommended a build manual from JW transmissions on powerglides and I bought it from Jegs for 43.00 and it is fantastic. You are never to old to learn. Lol.

Looking at the chambers, those are like the 1st gen Victors.........which I consider "easier" to get decent numbers from than the 2nd gen.

Rich - IIRC, you ended up with one MW and one standard port heads, right? And your goal is to have the standard one opened up to MW?

Brad, yes. Per Bob at Modern the cnc program makes them both the same, so that's the easy fix for mismatched part numbers. (Same casting number fwiw).
They're both this "older style" chamber ....your multiple links pics and threads about these heads were very helpful.

Dwayne, I hope they're good ones, once I can get the two heads to match

I think you'll find that even though the "casting" number on the heads are the same, you'll see that clearly they aren't cast with the same intake port.

If you had a set of dividers or snap gauges, I'd be curious to know how the bowl diameters compare between the two(about even with the end of the guide), and if the intake short turns feel like they are the same.

I've never had two of that vintage here at the same time.

The first set of Victors I worked on were the std port version, which were getting opened up to mw port size. They already had some minor bowl blending done when I got them.
I flowed one as rec'd, them did nothing but make the port opening mw size with a fairly gentle taper into the port, then re-flowed it.
No difference.

Unless a fair amount of porting is done(down stream of the opening) to the std port Victors, the port opening itself doesn't appear to be the most effective place to go after more flow.

Sorry if I fueled any misunderstanding.

Stated with a whole lot more clarity:

The claim that was made (which I repeated here)... was if both the standard and the mw heads are carved out in the cnc machine to be the same, then... after that operation has been performed, then the ports will be the same.

Is this not true/a promise that can't be kept?

The way Brad stated it isn't the exact idea (although I agreed with what he said-maybe I should not have). It's oversimplified. I wasn't just going to open up the smaller opening and call it good.

Actual goal is to create a matching set.

I understood what you meant, and I believe the std port head head would be a match to the mw head if both are cnc ported with the mw program.

My point was that even though the number cast into the top of the head is the same on the mw and std port version........ "As cast"....... They are not the same head.

Ok then we're on the same page.

Agreed, they're really not the same as-cast.

If I already had a matched pair as-cast, I'd probably just have the guides honed, intake valves backcut, do a light cleanup like I did with my rpm heads, and would just use them.

But...as you can probably imagine, I "got a good deal" on these.

Like so many other good deals, it will cost thousands to get things
in shape in running, but that's par for the course.

Oh, speaking of..there's another topic I'll email you about in a bit.

I've only had one pair of 1st gen mw victors in my hands, and my recollection of them was that the bowls were pretty big, which is why I was hoping you could measure them if you had the tools to do it....... As well as the std port head, to see how those bowls compare in size to what you get now........ Which are just way too small.

I will when I get a chance.

I recall reading the last critique of them here, it sounded like the latest versions were a step backwards.

IMO, they are a step backwards from a standpoint of....... "I'd like to have my aftermarket heads have decent flow numbers throughout the flow curve without having to have 'a lot' of porting done to them".

I felt like the 1st gen offered that....... The 2nd gen ....... Not do much.

As an example...... I just got some EStreet heads here.......the budget friendly street heads. The intake bowls are 2.050" for a 2.14 valve.

The new std port Victors....... The "race" head...... Have a ridiculously small 1.750"-ish intake bowl for a 2.200 valve.
Makes no sense whatsoever.

By comparison, a TF 240 head has a bowl diameter of about 2.190".
