[Toyoballs]

The 20-22R head bolts are not torque to yeild, and Toyota does not advise replacement evertime the head is removed.
I have reused head bolts for years unless they are rusted, and then I replace them with used ones!
In todays world of fancy engines, almost ever engine uses torque to yeild headbolts
The machine shop was playing it safe when they told you to replace them. Look them over carefully, and if they look good, you know what I would do.

Thanks Marlin, I defenitly respect your input This machine shop is repitable - they do warranty work for the local Toyota dealers and I never heard anything negitive about them. I just had a 85 EFI block, crank, rods and head done by them this past summer and they never said anything to me about head bolts then. I was concerned and wanted more info on the matter. They look good just need cleaned up. Thanks again
