Bearings, Gaskets, Girdle and Piston Rings... HELP!

Alright... I got a block and its time for me to get it all finished... It has bearings and piston rings and so forth but i dont know how good they are for turbo but I guess they should work...

18.1CC Dished Probe Pistons
Forged H beam Rods with ARP2000 bolts
Forged Cobra Crankshaft

Bearings are King Race or something... Supposively used in Nascars...
Piston Rings not too sure... But everything is new! Never used except the crankshaft... Block was all prepped and put together by TMD in california...
Im looking to get like over 600 RWHP... Is those Girdle things really necessary... I am going with a turbo kit!

what about the other areas??? So people say yes to Main stud girdle thing???

What about valves and so forth for heads... I am trying to build a 600+ rwhp motor... HELP ME OUT!!! I dont seem to get many posts...

BUMP BUMP BUMP!!! BUMP!!!!
