    I didn't mean to put the wind up you Rielly. If you don't want to do any more block mods you can probably leave it as is. Some builders just clock the front cam bearing at 11 o'clock to line up with the factory oil feed and clock the rest of the bearings at 1-2 o'clock. The main thing is not to have the holes at 6 o'clock as the pressure from the valve train pushes the cam down and blocks the holes, restricting oil flow into the bearings. Your engine guy probably knows this.

    I think the 3 o'clock thing came from some testing one of the oil companies did on Chevy V8's. There's a pdf doc about this, you could probably find it on a google search. They found that clocking all the holes in the cam bearings to 3 o'clock trapped the best wedge of oil between the cam journal and the bearing before the cam rotated round to the bottom. This probably filtered down to Holden V8's and builders started grooving the front cam bore to suit. Someone else can correct me if I'm wrong here.

    Anyway I've spammed your thread enough.

    Unless its a monster engine, you'll kill the cam or rings before you eat valvesprings, I would consider keeping the oil downstairs if you have to buy pushrods anyway but I wouldn't lose sleep over it.

    Restricted push rods work great, cheaper than sleeving lifter bores.

    If you have YT roller rockers you don't need restricted pushrods.

    There is a much smaller hole for the oil to flow through compared to the stock pressed metal rockers.

    I use -10's in each rocker cover to a single 2.5 litre catch can, it's never seen a drop of oil yet.

    YT rockers will still fill the rocker covers if you plan on driving it like you stole it.

    You'll be right mate but there's a lot to be said about a bit of mechanical sympathy lol,nice job on the tap tool btw, you'll
    find it can be handy not just for what you made it for but other jobs as well, i hate the T-bar drive that comes in the tap set with a passion lol!
