I have a set of new arp headstud I'm thinking about put on my crappy motor to try and fix a possible sealing prob. . I really don't wanna put them on this motor and save them for another 1.6 I can find or rebuild for boost. Are these things really reusable?? seal as good as the first time?

 

From what I've heard, you should be okay.

 

Tq them into the block about 30 foot pounds when reusing.
