I have an 84 6.2 I am putting on a Sidewinder 6.2 banks turbo kit. Is it safe to use the TTY bolts for the banks turbo? Or should I try the Arp studs again that leaked threw the threads?

What head gasket should I use? 6.2 or 6.5?

Note:I spent many hours cleaning the head bolt holes. The Arp thread sealer failed on me. If the TTY bolts will handle the boost from the banks turbo, I would rather use the tty bolts then take a chance with these Arp studs again... Can ya feel my butthurt?
