I've had Modern Cylinder Heads,586-468-7914, do three different types of BB Mopar heads,Eddy RPM, B1-BS and two sets of 440-1 They all made great power on the dyno and went fast at the track, faster than some others on here I believe Last edited by Cab_Burge; 11/06/13 02:35 PM.

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. https://board.moparts.org/ubbthreads/showflat.php?Number=7185404 Last edited by d7cook; 11/06/13 12:46 PM. 1967 Coronet, 1989 Daytona tube chassis.

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. 1967 Coronet, 1989 Daytona tube chassis. Former cars, 66 Charger, 67 R/T, 69 Coronet, 67 Dart GT. -Banned for life from V8Buick.com-

This is probably why your center divider is thin-because they are std. port Victors.

One of the ports has been opened up to Max Wedge size so the rest will need to be done. 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. Last edited by BradH; 11/07/13 11:44 AM.
