I got three questions....

1) what header bolts or fasteners are the best in your opinion?
2) what are the best header gaskets?
3) how do you secure your oil dipstick tube with headers? because mine bolted through one of the exhaust manifols studs.

 

1) ARP
2) Fel-Pro
3) I have SLP headers and there was a round bracket welded to one of the tubes. This held the dip stick in place. There should be another bracket at the bottom that bolts into the block right before the dip stick goes into the block.

I'd go with Blown's suggestion. However I think there is a set of header bolts that are lockable so if you think yours have a tendency to come undone now and then, try them.
