TD42 piston cooling squirters

[fleaster]

G,DAY COBBERS
new to this site,Have a GQ shorty im wanting to build a new engine for,have got a black top td42 engine n/a 1996,Vacuum pump under injector pump,as my donor,
just wondering if any one can tell me if the piston cooling oil squirters from a n/a engine have the same spray pattern as the factory turbo squirters?also can i just use silver top 30mm rods or do i need to find actual 30mm turbo rods(is there any difference??)
thanks for any help or comments
