Ba bf turbo cylinder head build

[Ammf6]

I’m in the process of finding a new cylinder head for my barra build. 

 

Ive got a turbo bf head which my builder said is to badly worn . my question is are all the cylinder heads from Na to turbo the same ?? I know the valves are different in the turbos . But are the castings the same ?
 

My damaged turbo head casting  numbers are 

- 3r23 - 6090- ac  

 

and I’ve just gotten a low k bf gas cylinder head with the same casting numbers  - 3r23 - 6090- ac  , the only thing that looks different with the two side by side is the turbo one has a cross / X pattern shape  on the front of  the alloy casting where the Na one is  just smooth . 
 

Are the Na heads fine to use on a turbo application with upgrading the valves and valve springs of course .

yeah, cylinder head is the same, just the valves and valve springs upgraded is fine... and studs while you're at it.
