W2 heads I think they are ready

Yellow rose is correct holes don’t line up.
Exhaust is not far off, maybe a .100”
Intake is not even close of course, with either pair of shafts, both were new sets, one was w2-w5 and the others I’m not sure, billet shafts I think not even close either.

Ok, that’s the picture I wanted to see. The oil feed hole in the rocker is just below the threads, and that is Chrysler oiling.`Crane made some rockers with the oil hole lower in the rocker body and that was bad.

Soooooooo...now you can see what I was saying about the clocking of the feed holes in the shafts...they don’t line up with anything. That hole in the rocker MUST be lined up with the hole in the shaft while the valve is on the seat. If you do that, you will be able to RPM as high as your budget or nuts allow (I crap out at 8800 when I’m paying the bills...someone else is writing the checks and I’m good for another 1k RPM) and as much spring load as you can get.

The only way I know to fix the issue is to mock up the rockers on the shafts they go on, and in the position they will run in, number everything, including the hold downs and then with some bluing on the shafts, use a thin scribe through the hole in the rocker and mark the shafts.

Then, you have to disassemble the whole thing, drill new holes in the shafts (you’ll need carbide as the shafts are HARD) and then you’ll never have an issue.

It’s sickening that chrysler didn’t address this issue. I tried grooving the shafts to get oil there, but it didn’t work.

My next engine will be a W2 deal, and I have to do the same modifications. What a PITA.
