There's no reason to do both heads. You do not need a Cometic gasket, they're meant for high compression and/or high heat motors.
Intake bolts are SOFT. I cannot count the number of people I've seen shear off the intake bolt heads.
Get a chemical bath ready and a big magnifying glass to check for cracks. Checking to see if the head is true is vital. If it's not, a machine shop would deck it for about $50.
It is a long drawn out labor intensive job. If you aren't absolutely confident you can do it, pay someone.
