Re-use of head studs in build

So we all know that my motor (block) cracked. Well I got an 04.5 with 55k on it and will be doing a mild build....my question is this...can I re-use the h-11 headstuds from my 03 in the 04.5......I believe the size is the same just want to make sure.......While the motor is on the stand I am going to check the bottom end, replace some bearings if needed, add a stage 1 cam, stage 1 valvetrain, port the heads, port the manifold and port the exh manifolds, add chromoley pushrods, fluid dampner and new injectors. I am going to heat coat the exh manifolds, valve covers, intake manifold, down pipe, Inter cooler tubes and intake horn. I figured I would get away from the OUTLAW build since I picked this motor up for 2k......the motor has been trouble free for the owner.......I figured the cam and valvetrain will allow for an increased power range, porting everything will alow for the air I need for the injectors, lower egts, lower boost pressure and increase HP while heat coating everything will increase spool up, lower egts and look good. Fluid dampner to smooth things out and quiet it down a tad....With a good turbo and my water meth this thing should produce in the 500hp arena....What do you all think about the build?....Will the head studs work on the 04.5 that were in my 03? I think its the best, cheapest way to get this thing back running......the turbo will come after its completed and running....

As long as you have not overtorqued them and you use a moly thread lubricant you can reuse them. Same goes for the ARP studs. As far as the number of reinstalls, you would have to call the manufacturer. ARP wants 3 equal torques to specifications. I would assume the H-11s are the same. If my memory serves me right final torque is 245 ftlbs.

Contact the stud manufacturer and they will provide the specs for measuring the studs to make sure they are still good. Most times they are re-useable, but it is definitely worth checking them.

H-11s are tool steel and are re-useable

I'm not trying to sound like a d*** here, but you are spending thousands and thousands to get all that stuff done, and you want to re-use the head studs? It just seems like a bad idea to me. I would sell them, and get a new set, personally. I wouldn't want to risk all that work on a faulty stud. It's not likely, but it *could* happen..

ARP's can be re-used but the steel isn't necessarily made for it. They are torque to yield studs IIRC, just like the factory bolts. Any H11 is tool steel and they are designed to be reused time after time. If it were me I'd reuse them in a heartbeat.
