I have a pair of Edelbrock Gen 2 Hemi heads on order through Hughes Engines who is setting them up for me. Is it possible to have these push rod channels opened up a bit for more clearance? I'll put it on my list of questions to ask Hughes when / if Edelbrock finally starts up production again.
Thoughts on clearancing prior to assembly?

"i just cant bring myself to buy a stock type mp aluminum head"
I haven't personally had access to the Chrysler parts system since '13, and can no longer physically check it out myself, but if I can believe what folks have said offhand it seems MP killed those part numbers off anyway, and that's probably no longer an option (unless you find someone who already has them). So, one less thing to worry about I guess.
"Is it possible to have these push rod channels opened up a bit for more clearance? Thoughts on clearancing prior to assembly?"
Sure, most anything is possible (Whether it is practical or not is yet to be determined). It's a thin brass tube pressed in. You can potentially press or cut the tube out, machine the hole bigger, hope you don't get into water and so on, and press something else larger in. You can CNC the holes into an oval shape, and then custom make 8 special oval shaped tubes to press in. There are many possibilities. Just nothing that I would do.
The engine was not fully assembled in the pictures shown, it was one of many mockups. Multiple mockups and corrections were done.
With the Victor Jr, one thing a person is not going to do successfully is stick a carbide bit in there and cut away at the casting to create some more clearance. Again, It's a brass tube.
Instead of the above, alternately, an exhaust rocker other than Indy also seems to take care of it.

I just built mine using Vic jr’s. Barton told me to run his 1.5 rocker on the exhaust. No clearance issues what so ever. .700 lift roller.

Yeah, those were also recommended to me per discussion with local race engine builder/guru. Before I purchased my heads I was fortunate enough to be given a guided tour of new and old TD/Barton rocker setups and an explanation of how they've evolved, they are super nice, but out of my league financially as I needed to spend that few thousand bucks on Sheetmetal for the car more.
Indy shaft roller are the only one I know of with the interference problem shown here, it's just a certain combination of parts to watch out for, thread was intended for information.
After a few more years, are you still satisfied with using the stock 426 non roller tip rocker arms with the Victor heads? I finally have my BMP 4.5 bore block, and have Victor Jr. heads on order... the current plan is a 10.5:1 572 for my fake 71 Cuda.

I'm very satisfied, but the statement is pretty meaningless because all the engine has done is hold down the engine dolly while I restore the car I'm installing it into.
I've fired it up without installing it, seems to run well, but that's about it, it's mothballed until the car is ready which will be awhile.

I have 7/16 D.T. X. 165 wall in my Hemi with Mopar (Edelbrock) heads with over .800 lift, street driven and strip with the RBRE rocker system with no issues shifting at 7600 thus far. The RBRE rocker system helps take out so much of the push rod angles and corrects most of the geometry.

Those blue rockers look so much sexier than the natural finish they have now.

Their first batches were blue, then I believe they went to red, then I am sure due to cost they decided to leave raw (and even charge more for them). Lol. They are now over $1000.00 per set more than they were back when I bought mine.

The RBRE rocker system helps take out so much of the push rod angles and corrects most of the geometry. Do they fit under somewhat stock appearing valve covers? To anyone with even minimal hemi knowledge my car will never be anything other than a fake, but to a typical 5.0 mustang owner I want them to believe it is a stock 426 with a '3/4 race' cam. I am going to be using iron exhaust manifolds, mechanical fuel pump, clutch fan, etc... Note: I feel it is fair for me to call a 3/4 inch cam a '3/4 race' cam I am not ready for a 1 inch cam, commonly referred to as 'full race'

Do Stage V roller rockers on an Eddy Jr head have the same push rod clearance problems, I believe their ratios start ar 1.6 but not sure if there are 1.5s or 1.55. The TD are very nice and a friend has them on he 572 Hemi in his race car with the spray bars. I believe both oil via push rod and spray bar is available from T&D just the price is higher that many want to pay. Stock Type rocker from Mopar can be an experience testing to see how close they are in Ratio. Indy is a no for this type of set up. Those guys from Canada HemiGuys that sell both a Roller and Wide pad type of Hemi Rocker anyone used them on a good roller hemi set up with lots of spring pressure and did they survive. Looks like I am going to mock up and see if there is a contact problem in the Push Rod Guide. It was easier to run a 426 Cast iron motor then to go big 572 with Aluminum. Stage V heads out of FHO likely does not have this problem do to the size of the work Banning does on the push rod bushing. This is a good read and anyone used these parts BMBlock, Eddy Jr. Heads should make this a read before ordering or assembling.

I've put several together with Victor Jrs and Stage V's. (Their standard 1.6) The engine on my test stand has that setup today. It is really, really close but I've never seen any witness marks on teardown.

This is a good read and anyone used these parts BMBlock, Eddy Jr. Heads should make this a read before ordering or assembling. Where can somebody find this read? Thanks What I am saying is this thread is a good read. When Banning lived in Bewley, Ontario we would go there a lot. He would put those tubes in the Stage V Heads but were much bigger for a larger push rod. So the problem seems to be on the Exhaust side of the push rod tube. Lowering the ratio seems to fix the problem with some rockers. I wanted to go the Stage V rockers way and might have to give Banning a call and see what he thinks and if Stage V has a 1.5 exhaust Rocker or something atleast under the 1.6. The final thing will be to mock up the motor and take alook at what clearance is there. The only problem with T&D is the price but you only want to do it once and not have to do it twice if something happens. If you go with a stock Factory type rocker then who would sell the most accurate ratio or is it just buy and hope things add up after checking. Quality control at it best.
