Head Bolts

Was wondering if anyone could help me i just got a new head and replaced my pistons and connecting rod bearings due to engine smoking on start ups. I was wondering if i have to replace my head bolts, the reason i ask is because on Toyota 22R engines they use stretch head bolts that need to be replaced every time they are removed.

As many engines as I did, I never had a problem reusing the head bolts.

This question has been asked a zillion times.
They are not torque-to-yield bolts, and can be reused several times... if they haven't been stretched.

Thanks guys
