Oil feed and restrictor from head

[ctspoolintsi]

Ok i have a gt12 ball bearing turbo and currently feeding form the head but havent put any miles on it yet because i been looking up and told i need a .35 restrictor so i did some research but i cant find my answer.

I do not want to take the current fitting off the turbo ( its kinda messed up but does not leak and its a real pain spot to get to) So my question is.

Can i feed from the front of the head ( oil galley plug ) and make that fitting that goes into the head the .35 restrictor.

So it would go Head --- .35 Restrictor --- -4 Line to turbo --- normal fitting thats on turbo ---- Turbo . ? do they make that i believe the front of head is 1/8 . So do they make 1/8 to -4 .35 restrictors. ?

My main question is can i run the restrictor off the head then have it go threw the line into the turbo or does the restrictor have to be at the turbo .

I don't think that has to be at the turbo only, from what I know the restrictor can be either at the oil filter housing, head or turbo
