I’ve got a set of iron W2 rockers I’m not currently using if they’d help you.
New 408 build finally started

Appreciate it but I’m pretty sure they would be even less offset. I’ll take a break from it and rethink things. My other set of heads went 9.74 on a worn out block in Pa during the summer. They just need me to touch up the valve job and check the springs out.
W2 rockers are .750 offset.

Been a bit since I’ve seen the HS stuff but IIRC they use a different diameter shaft than OE chrysler don’t they???
If it’s the same you can use a W2 rocker next to the HS exhaust rockers you have, although the geometry is different between the HS and the ductile rockers.
Damn...can’t think of a quick and dirty way to get this done. I’d love to see how this turns out.

I know it’s a little ways off yet but are you planning to put this engine on a dyno? I’d LOVE to see what kind of steam it makes.
My guess is he will use the track as a dyno.

In post 179 you mentioned using the Indy 360-1 style intake gasket for marking the ports in this head. Doesn't that mean you made these heads just as wide at the pushrod and now require the same rocker offset as the Indy 360-1, at around .800" offset? I am just spitballing here. Hope I do not make it more confusing. Really want to see this one completed.
Good technical posts like these, even when things don't go exactly as planned, are very interesting to me. Better for reading along than most books.
Hmmm. I have a set of 360-1 T&D 1.6 rockers on my shelf I bought from a guy on Moparts that had an engine blow on a dyno. I was planning on upgrading the Indy 360-1 rockers on my 422 when I rebuilt it. If I get the itch today after my walk I will grab those rockers just for some test fitting. Thanks for the suggestion as I want to have all angles covered when I call Harlan Sharp hopefully later this week.
Ya I’m not much of a dyno type of guy. One way or another it will hit the track when and IF it ever opens.
I’m pretty sure all the heads use 7/8 inch shafts except for the T&D individual shafts and the are 5/8 I think

I for one would just like to say thank you for you showing us all that you have in this thread, it couldn't have been easy to post this latest hurdle. It's easy to show our successes but for me at least it's a lot harder to show where we fall short. But I have no doubt you'll work it out.
It hasn’t been easy to get myself motivated the last couple of years. Between health issues that started in late 2016 and getting hit from behind last June in moms car and getting a concussion it takes the wind out of your sails. I kinda figured the way my son was talking he wanted to race his car this year but he has been sitting in front of the tv everyday since getting laid off two weeks ago. That pisses me off more than anything. He finally signed up for unemployment yesterday and has yet to file his income tax. And he has money coming back.

Maybe it will help your motivation to know that reading these technical threads has finally motivated me to get off my *** and get my car back on the road after about five or six years sitting. Mine wiped a cam lobe and I took it apart, then it sat for a few years. Even had birds get in my barn and crap all over my car.
I just spent Sunday filing rings and checking bearing clearances on the rebuild.

Thanks for sharing! I totally understand that kid thing, I have three of my own and if I didn't call them I don't know that I would ever hear from them. You raised them and think that when they grow up things will change but I worry about them more now then ever I think.
My son moved back in with me last January after I told him to move back home because he was struggling financially. During that year he never once touched his Duster. Now a year later at the age of 31 he is still broke and the only bill he pays is his 200.00 truck payment and effective January our 175.00 cell phone bill. He doesn’t make big money (19.00 an hour repairing fork trucks) but living rent free he should have money. His truck has been parked at a friends house for 1.5 years. Beer, shooting pool and throwing darts is his priority. Hopefully that changes.

So I've had my own strange issues in the past that I've had to work through and have been following this one a bit. I've dealt with the pushrod pinch on a number of different heads.
Looking at your new rockers and then looking at these, I think there is some to gain from different rockers.
At this point, I believe I would stop, get the rockers with the max offset that I can - or that I'm comfortable with the pushrod laid over - keeping in mind that I'm loosing lift. (My W2 stuff is all gone so I can't help with parts.)
Do what I need to do to the head (if anything) to get the pushrod in - that's the purpose of the exercise - and then fix the head. Too much work and potential to throw them in the corner.
As far as the other issue, I've become OK with walking away from folks who aren't on the same page as me and/or expect me to carry them while they screw off someplace. Don't want to participate? That's fine. I have s#!^ to do, I'll see you. Family doesn't get an exception. This racing stuff isn't easy and it doesn't go along with hanging in the bars and sitting on the sofa. You're either motivated or you're not. Lazy people are a distraction.
I'm only a couple of years behind you. I don't have a lot of time to pi$$ away on foolishness.

My engine builder used the Hughes rockers to suit the relocated pushrods. Seemed to work ok
.680 solid roller. So far so good

I was kinda worried when I check out the recommended max spring pressure on those and using a roller cam.

If HS has any of the TA intake rockers in stock....... you could buy just one and see if it will be a solution for you.

John, I have a complete set of new in the bags, crane gold race rockers for w2 heads. If you can use them for mock up I would gladly send them to you. If you decide to use them we can talk later about cost. Call it a thank you for this entire post.

Sorry I failed to mention mine is a street solid so probably less spring pressure than yours. 268/274

I just had a thought. Remove the exhaust rocker and pushrod to get them out of the way. Use feeler gauges between the shaft hold down and intake rocker arm, on the intake port side. Keep adding feeler gauges until the pushrod goes in and you have ample clearance. My guess is the .350" you already have built in plus whatever the feeler gauge reads should be the correct amount of offset. Does not cost anything to try, and should show if a reasonable offset will work.
Appreciate the help and suggestions. Just for the heck of it after my walk I grabbed a set of Harlan Sharp rockers I have here for my Indy 440-1 heads. I pulled the rocker off those shafts and tried it on my Edelbrock shafts. Spacing is way off for that application. I tried my T&D 360-1 rockers and with those you have to use their shafts because they use spacers to fit the rocker pedi stools. No go there either. Not sure if the guys at Harlan Sharp are working now or not but talking to them will be my next move. No rush on this project now.

With regards to Indy house brand rockers(the Dove rockers), I’m pretty sure the 360-1 rockers and 440-1 rockers are the same.
The spacers and hold downs are probably different, the shafts are different, but I believe the rockers are the same.
As such...... they should be too long to work on a stock style SB head.
One possible issue I see that could arise from using W2 intake rockers would be if that moves the pushrod over “too far”, and you end up with some interference with the pushrod and the intake bolt.
