OK - we may never use them again but always good to have the OEM part for reference. Once material gets plastically deformed, it reduces characteristics like tensile strength and can also affect torque values. Rust, dirt, oil, all contribute to inaccurate torque readings. Next time I do a block I will invest in the exact hex bolts Just8Ns sells. I've seen some snapped off studs in blocks that take a specialist to retract without boogering up the cast iron head threads. The studs are hardened steel.
