[DeTomaso] oil restrictors

I did a lot of research when I built my cleveland a couple years ago, most of it was through the internet but i was very critical of what I read.  i too built a cleveland with roller hydraulic lifters.  here are my conclusions:
I bought the moroso oil restrictor set

It seems that the modification where you run a line from the oil plug just above the oil filter to the rear of the block does not serve any purpose.
I had my engine block guy drill a small hole in the oil plug by the distributor to oil the gear.  Easy to do and no harm.
I chamfered the oil drain back holes in the lifter valley myself - easy to do, oil drains more quickly.  I guess a high rpm serious motor would not want oil falling onto the crank to minimize windage, but for the rest of us this seems good.
i tapped the oil passage between the crank and cam bearing at the front of the block, and placed a restrictor (with a small hole if I remember correctly) down in there.  This is all outlined very well on the network54 cleveland forum and makes a lot of sense.
For hydraulic lifters, I am pretty sure you should restrict flow to the lifters, so if I remember correctly, I did not use those restrictor(s)
I also placed the oil pressure sender above the oil filter instead of at the back of the block.  maybe this is less valuable oil pressure reading but it looks nicer hidden away.
Let me know if any questions since I might be remembering something wrong.
I'm using a regular oil pan since I am not racing at all.
My engine runs awesome as is and hasnt blown anything up yet.  only a couple runs to 6000rpm so far, but it should hold together...
