(It would appear the post that I’m responding to here has been deleted.
Apparently the rocker shaft fit in the saddles is a bit loose, and the poster was unhappy that I didn’t catch that when prepping the heads........ so this was my response to that.
I figure if this is a potential problem with these heads, then that’s info that should be out there, so I’ll leave my response up to highlight the fact that this is something that should be looked at.)

I’m the “head specialist” in question........ if you’re referring to the particular heads in this thread.

There isn’t really any excuse for not catching this issue, other than to say it’s something I’ve never come across on any Mopar head I’ve put on a motor in 38 years.
Frankly, the shaft saddles not being machined to the correct size never entered my mind.

Also, just the be clear........ I didn’t sell these heads.
I was contacted about whether I’d be interested in prepping a set of these heads, so I said “sure”........ and a few weeks later the cnc’d bare castings showed up.

To my recollection, I never had the rocker gear here that was going to be used on these heads to test fit any of it.

If the saddles are simply machined to a slightly larger diameter than they should be, you should be able to lay some shim stock in there to properly locate the shafts.
And if the hold down clamps are machined to the correct diameter, I would think it should work fine.

Another possible solution would be to contact Mike at B3RE to see about having some shaft relocation spacers made, with the lower arc of the spacer made to match your heads.
He’d likely instruct you that you need the spacers anyway, so it would just be a matter of whether he could match the arc of those saddles or not.
