turbo oil feed and drain advice

I have ordered a new oil drain seal for block .....for refitting standard solid pipe.

But was unsure whether to bite the bullet and make lines both feed and drain.
At what level do standard become a restriction or are they only for peace of mind.

found things like this for feed line.

Drain probably a 10an threaded to block.

Does anyone on the forum make lines up? Rather give people business then buy elsewhere.

I still use the standard oil drain into the block modifies onto the turbo and a braided feed line with a ristrictor.
