They all made great power on the dyno and went fast at the track, faster than some others on here I believe

FWIW, who I trust to work on my heads has nothing to do with whether they CNC port them or not.
What type of heads are you talking about?

Why is the port divider wall so narrow?
Do you have a measurement you can share on the width of that?

And what head is that with no pushrod bulge?

I wondered the same thing... looks too narrow IMO for adequate gasket sealing surface.
EDIT: Yeah, I know WHY it's narrow, but still was concerned about sealing issues.

I don't mean to sound like a smart a$$ but to make the port bigger. Only so much space to work with. They started out life as standard port Victors.
Yes it is thin but I've ran them this thin on other heads without a problem. You have to be careful cutting out gaskets but I've never had a problem with the gasket blowing out. I'll measure the width tonight.

I though the same thing,thin divider wall.Not only do you have to be carefull with the gasket fit but manifold match also.Keeping that alignment you may find it nescessary to add alignment dowels to the head and manifold to make sure it it returned to that precise position when it is removed and replaced.Why not start with heads that are cast for large ports to begin with?

They are the standard ports. One of the ports has been opened up to Max Wedge size so the rest will need to be done.

2.725x1.44 port size. 1.1 divider. Yes it's thin but I've had them that thin before without a problem. You are correct in that I use a dowel. I always drill a dowel when I port match and intake to a set of heads. I have two intake set ups right now. One is a 400-2 with spacers and I counter sunk the inner two bolt holes and use flat head screws which locates it. I drilled and tapped two additional bolts inboard to bolt the intake to the spacers. Other wise you can't get the long bolts to work with the port wrapping around the inner two bolt holes. The other intake is a super victor that I haven't port matched yet.
As far as which ports to start with Modern asked that the std port heads be provided even though they were gong to MW. I assume its easier to take a thicker cut off the aluminum.

I don't see how that is possible considering the Eddy's are two seperate castings with the pushrod hole machined in a different position. This is probably why your center divider is thin-because they are std. port Victors. J.Rob

Combination details? I'm asking because I did some research into what CNC offerings are out there for Victors (not many) and what I did find was predominantly for MW-sized ports anyway.
Some seemed focused more on big high-lift #s (e.g. Speier Racing Heads), whereas the Hughes program seems more oriented to more moderate lift requirements.

The same rocker is used for both heads so I don't see how the pushrod hole could be different. I've never had std port and a MW port head next to one another to compare though.

Re: CNC porting - 11/07/13 04:02 PM
All I can add is that T&D now specifies two different part #s for Victor heads depending on MW vs. standard, and the MW version uses an intake rocker w/ more offset.

OK, you're right then the MW pushrod hole must be moved .075" outboard I assume. When I bought these heads I think the MW version had just come out.

The combination will be a 500", 12-1 with about a 670 lift solid.
