21HP V-Twin Head Gasket Repair

[TwinL]

I just picked up a Craftsman LT1000 with a 21HP Briggs V-Twin, model number 407577-0283-E1. I believe it needs new head gaskets, I have ordered the gasket kits but I was just wondering if I need to order new head bolts too? In the past I have ran into issues reusing head bolts and them snapping in the block while torquing them down. I was also wondering what the torque specs are for the head bolts, and how many stages I should torque them down and how many foot pounds for each stage. I’m 18 and fairly new to this, so any help would be appreciated.

I know these engines are famous for the valve guides sliding up jamming the rockets and bending the push rods, usually the shroud over the fly wheel has gotten filled with crap, quite often caused by mice causing the engine to overheat, the head bolt torque is 220 Inch pounds, that's "Inch Pounds", I've done many and used the original bolts and never broken a bolt off.
