Valve train oil passage bolts

[angeldust72]

someone mentioned that the rocker shaft on my 340 has special bolts for the oil galley that supplies oil to the shaft (second pillar back on the driver side, second pillar forward from the fire wall on the passenger side) that these bolts ( that tie down the oil shaft) are either hollow or are tapered to let the oil flow around them?
Any truth t this rumor?
If I don't have them installed, will I not get oil to the valve train?
Where would I get them if they exist?
Anybody got pictures of them?

I made a set for my 273 years ago. I just ground a taper in a grade 8 bolt.

The stock bolts are all the same. They allow plenty to go around them. When they are replaced with studs, they can get restrictive. I find cam bearing hole alignment more of an issue then the bolts. It can be a problem, but it's not that common.

look down in the hole( 2nd from the front/back) and you will see how it's
made...the shaft has a little bit larger hole for this position and that's why they tell you Notch down and to the front on the right and visa versa for left.
It's the larger hole on the bottom of the shaft that your matching up...and all this is over if they didn't match the cam bearing up like moper said
