Great.Plenty, the shaft will fill and pressurize.
Just disassemble the rockers and assembly lube it for ever cold start 1st..
Joke.
Theres a head bolt trick you can do to bring more oil by it. Index mill the shank. Torque it, mark the bolt hex head in the direction of the oil feed hole, remove bolt and machine a flat on the non threaded portion on the side of the mark you made.I'm looking at the oil feed holes to the rocker arms and they seem small.They are around 1/8" in diameter.Has anyone running these had any issues or drilled them bigger?

Mine were not getting enough oil and was wearing out the rocker bushings in my prw rocker arms
Both prw and Mike at b3 recommended that I change the lifters out to pushrod oiling to help with that.
So far so good!
I bought the Rocker arms from Mike and he was able to warranty them for me.
I would definitely recommend that you talk to him about that..
He sounds like he's talking about not getting enough oil the adjuster/adjuster cup/pushrod cup , depending on which style he has.We’re you running a standard or HV pump.

So he's bringing oil through the pushrod/through the adjuster to fix his shaft rocker bushings wearing out? Neat trick.He said he was wearing out the bushings.

Magnum engines don't have shafts. I'm not saying its unheard of to oil through the rockers... 'just to fill the shafts is all'Lol
Like I said,
Both Mike at b3 and prw recommended
Adding pushrod oiling to get more oil to the shafts.
The adjusters have oil holes in them as well as the rocker arms that feeds the rocker shafts..
That's how magnum engines get oil there.
Anyway it solved the wearing out bushings problem for my Engine.
Your rightMagnum engines don't have shafts. I'm not saying its unheard of to oil through the rockers..just to fill the shafts is all.
I wonder the cam bearing is aligned ..
Your right
Thank you , I meant that it does oil through the adjuster to the rocker arm bushings also.
Maybe it has a cam bearing not aligned just right like you said?
But it seems ok now.
I will say that while I waited to get the warranty rockers back
I put on a set of 273 shafts and rockers
I drove it with those for a month or so
They showed no sign of wear at all.
That was before adding pushrod oiling.
Thank youYeah, there was something else wrong there. I run that exact same rocker and I’m not getting after the shafts like that. That is lack of oil.
I’d be concerned that a cam bearing wasn’t installed correctly or it turned in the bore is is at least partially blocking the oil feed hole to the head.
Could be nowIsnt oiling through the pushrods the preferred way of oiling with TF's? I am putting together my 408 and plugged the block so shaft oiling isnt possible now. Running TFs with HS rockers.
