I have done 3 cams to date and wasn't able to strip a cam bolt. (Looks at Mike funny
It'* new chain/gear set or nothing IMO>
You forgot the Boosty option for $1,000.
Get some cam lube if it'* not in the kit. The lube is basically a thicker weight oil like 20-50 or straight 50. Plan to do the swap all at once so when you pull the lifters they go back in the same day. That way they won't drain off too much oil.
If you need..I have a WP gasket, although you shouldn't have to remove the pump..only 4 of the bolts (the 13mm ones) If I can recommend... toss a higher oil pressure kit in there. It'* a spring/washer/slide and brings your pressure up to help ensure the life of your parts.
