Fred,
I agree with your comments about head bolts and in particular head bolt
nuts and washers. I retained my head bolts, as they passed the test of
spinning a new head nut down the bolt to check for thread stretch. But I
did replace the nuts with new black ones from TRF and used new grade 8
washers.
But, at least for TR4s, I did not see the need to replace main and rod
bolts.... if they were not damaged for reason.
