I just built a motor and didn't worry about it. From what I've read Pred is right, not really necessary unless you're heavy, heavy into what you're doing. But then again, I don't think it really hurts anything either so do whatever you want to.

I have done a few h/c installs and never did it, Thought about it but didnt. It wouldnt hurt anything if you did do it 
So i will do it to my car down the road.

I didn't. I don't like the idea of drilling a non-metallic part that could crack and is the only thing keeping my lifters in alignment with the cam. If you want faster drain back, get a link bar lifter.

Morel lifters are about the best ones out there, but they are not cheap. PM sent.
Also, Fraser at Speedinc has them, here is a link to his thread with a photo. Link

I have drilled the drainback holes in many DD engines with no bad results. I currently have my DD drilled, it has 78,000 trouble free miles. A link bar lifter will most likely break way before 40,000, so using them in a DD is questionable.

I have never broke a linkbar unless something hit it.
Failure 1. I put 3 sets of linkbar hyd lifters in a boat with 3 engines in the mid 90's. After about 100 hours of use it had a slight tick that lasted about 20 minutes and finished with the engine backfiring through the carb. I took the one engine apart and the link bar was whole but not connected to one of the lifters anymore. It was kind of mangled from spinning. The other lifters had pins that also had worn part way, some worse than others. The other two engines showed the same wear, but had not failed yet.
Failure 2. Chevy V12 corvette with std SB link bar hyd lifters. Unknown miles (guess less than 10,000) but probably was run to valvetoss more than once. The linkbar was again whole, but the pin connection was broken off. I called Falconer for a replacement set of lifters, he said they keep failing the link bar and sent me stock oem lifters and a dogbone guide that I machined the block for.
With newer material they may last longer than in past years, but the oem style will go 100,000+ and does it daily.

Having the lifters in a bath of oil in trays actualy reduces lifter bleed down rate, which is a good thing for traffic, keeping your lifters pumped up longer.
Like I said, if the goal is faster oil return ib drag or high G situations, yes, otherwise it is better not to do it on a DD that is in day to day traffic.
