Are these any good. doing h/c and i was told bolts can only be torqued correctly once, so would these be a good replacement for a mild motor? only mods are mid tube headers, borla catback, k&n, and lt4 hotcam, 1.6rr, dual spring p&p heads.

id much rather reuse them if i can. but someone on another forum said they can only be used 1 times, prolly due to strectching.
i like arp as well but 60$ for some bolts is steep.

Clean parts, new gaskets and fresh bolts are always a good idea.
You'd be taking a risk reusing stock bolts.

Torque to yield (TTY) bolts, also commonly referred to as angle torque or stretch bolts, are used in many of today's modern engines predominantly for cylinder head bolts but also main bearing and big end caps.
Compared to conventional type bolts, TTY bolts offer the engine manufacturer a number of advantages including greater flexibility of design, reductions in component costs, more accurate assembly and reliability of seal. Engines designed utilising TTY head bolts require fewer head bolts to achieve the desired clamping loads then those using conventional bolts. With fewer bolts the engine manufacturer has more flexibility in cylinder head and block design as well as reducing the cost of the engine.
Whilst TTY bolts are attractive to the engine manufacturer, there are disadvantages to the engine repairer. For the most of us it would be unthinkable to replace a conventional head bolt unless the bolt was damaged, i.e. stripped threads, the bolt head was rounded off, the shank was severely corroded or pitted.
Conventional head bolts simply just did not wear out. Torque to yield head bolts however, by the very nature of their design, do wear out and should NEVER be reused.

And to reuse your old head bolts multiple time is kinda like reusing a loaded condom. It wil work but it really is not the way it should be done because it is dirty and worn out.
