Hey Fuzz401, is that a RollMaster Timing Set ?
I guess the Torrington Bearing doesn't starve the Dizzy Gear for Oil ?
Just for reference, I believe the the (6) 3/8 Pipe Plugs needed in the block are there to plug holes
that are used to give access to drill or ream the oil galley passages into the block during manufacture.
As they've said, they must be in place to seal up the oil galley passages to get pressure.
The stock pipe plugs have a square socket hole rather than a hex socket hole.
If a person wants the square socket hole 3/8 pipe plugs, they're hard to find,
but they are available from Au-Ve-Co, box of (10), Part # 16307, $5.95
It does sound like they've been left out of the front of the block.
They are usually taken out when they clean the block.
Be sure all (6) are installed, (2) front, (2) rear, (2) in valley at front wall on top.
Have heard of people using an EDM machine to put a very small hole
in the front ones to increase timing chain oiling.
There absence would explain not getting oil to the rockers, no pressure, and oil coming in the those front holes.
