I wouldn't risk it because the tubes are brazed into the joint. If you do though just be careful. You'd have to find out the angle/pitch of the NA version to run yours to be alike. I'd suggest at best if you can find an NA that has been parted out to buy a set of those and run them. I suggest soaking the squirters in solvent for 48hrs...then run them through a sonic cleaner. Blow air through the holes then you are done.
All of the parts I clean go through this method...especially the oiled products/parts. Solvent/vibratory shaker/solvent/sonic cleaning/solvent then dry. Its pretty lengthy process but my parts come out spotless and I'm guaranteed a clean productive part afterwards.
