This has become another engine rebuilding dilemma for me. I have searched many Chevy hot-rod/racing forums and the responses are almost 50/50 for/against reusing head bolts.
Here is the specific question for the poll.
If the heads in question are OEM Chevy 350 Vortec's and use TTY (torque to yield) bolts AND the motor is being rebuilt to stock/OEM performance standards...is the installation of new bolts really necessary?
The cheapest set I can find are $35. The "good" bolts (ARP) can run well over $100! I question the motives of those who manufacture and market the TTY bolts as just another way to profit from the ignorance or fear of unsuspecting home mechanics. BTW, I already know that the "industry" says I must use new bolts. However, my machinist says, "BS, clean and use the old ones." As does a number of Chevy wrench turners on their respective forums. Opinions and experiences from iboaters are appreciated.
