You do know that a lot of the factory bolts were graded bolts right. LOL. Give me a break.


Into cast iron???? Which ones????

You don't use grade 8 bolts into cast iron per all the fastener training I have been through. You want to do it, that's fine, but don't give the OP bad advice.. I prefer to to use precision practices with everything I do (including using proper hardware) and it has served me very well in life...............
