Retorque the head bolts?

I'm gonna be doing a cam swap in the next week or so. As most know, I did a new HG about 100 miles ago. I figure it would be advisable to retorque the headbolts.

I was wondering though... with FelPro TTY bolts, what torque should I wrench them to? The conventional 90 ftlbs?

What would YOU do?

I thought that you aren't suppose to retorque tty bolts... Hopefully an expert will chime in

Do not retorque... AFIK that's the main reason TTY bolts are used...

When turned the last 90*, the bolt actually stretches and will not quite assume it's original length, each time it's torqued it "grows" a little... I've heard every thing from they can be reused up to three times, to use once and discard...

What did the instructions say???

I'm in with TurboCoupe50. I've heard various recommendations on the TTY. Go with the instructions

That does figure, I guess. Instructions say no retorque, ayeaye!
