Probably doesn't matter, but I'm pretty sure the lifter galleys are fed from the rear. So, facing them all to the rear would be the anal retentive thing to do. :D That's how I did mine.

Even though the general consensus is to face the oil holes to the rear, in reality, it doesn't matter. Once oil pressure is established in the engine, the oil groove around the lifter becomes pressurized and will feed the oil hole from any direction.

Yep, that is why I deleted the post...lol.
As soon as I hit send, it dawned on me that we are not talking a flat tappet with these engines..:confused:

I was just yesterday talking to an NHRA Super Stock racer who
must use a flat tappet design. So while I was drinking a cup of coffee today,
I noticed this discussion and my mind went right back to that discussion.

Getting difficult to multitask at my age..:p

Anyhow, dBomm correctly set things straight.

Cheers to all!
