head bolt washers
Should I use washers on the head bolts on a CAST IRON head? 1926 Roadster.

Re: head bolt washers
Ford did not. But after 100 years of bolts being tightened, I had to have my head bolt bosses refaced and I now use hardened head bolt washers, except for the headbolts at the coil box brackets.

Re: head bolt washers
I don't like the idea of using them but I did to make sure I didn't bottom out the bolts. I chased the threads and did my best to clear the bottoms of the holes but a couple were questionable depth-wise. One I had to double washer. I had more issues with head gasket sealing before I did all this, than I do now.

Re: head bolt washers
I think it a combination of how many times the head has been planned (faced?) and how may times the bolts have been used (stretched), so washers do have a place to ensure you get proper pull down.
Clearing the holes is important, it surprises me how much gunk comes out of holes that spend most of their life containing the head bolt.
