get ARP bolts if you can. Felpros are also nice.

the way I did mine to stretch them properly was to torque (in sequence) to 25 ft lbs, break them loose, torque to 45lbs, break loose, then torque again to 65 lbs.

for the actual gaskets themselves, get the Impalla LT1 head gaskets, they are slightly thinner and will give you a bump in compression after install.
all total, when I did mine, I think I spent around $150.00 for every thing save for the fee to use a stall at the hobby shop on base.

here's when I did mine

other things to keep in mind

The gaskets go on serial number up. If you get Felpro's, they're marked.

don't forget the bolt that holds the ps/ac pump and alt bracket to the riders head. Matter fact, you'll probably have to loosen the whole bracket

you have to take off the intake, y-pipe, exhaust manifolds. You can leave the fuel rail on the intake but its easier to get the intake off with the rails off. You will have to get all the top wiring out of the way for removal and cleaning. Make a template out of cardboard and place your intake manifold bolts in the piece of cardboard just as they came off the intake. This will help you when your reinstalling all of your stuff As said there are torquing sequenses and patterns for both the intake and the heads so you need to follow those to the T, and putting the sealant on the bolts are a must. I have always used ARP head bolts and since you cant get back in there to retorque the head bolts I always torque them down and then loosen them all back up a total of twice and then torquing them down for the third time usually will stretch the bolts enough that they will not work themselves loose. Also depending on what bolts you use for the heads at least use engine oil as a lubricant when your torquing them down or you wont reach the correct torque. cleaning the threads out on all the areas is a must. You can just go buy a thread chaser to do this which isnt too expensive. Its a tedious process but definitely worth it for sure. As for the passenger side head, you will need to take the accessory bracket all the way off to give you enough room to pull the head off easily. Dont forget the crossover bolts for the steam pipe in the back of the heads. They are 15mm and if you can get your hands on a ratchet wrench they work wonders I cant stress enough that while your in there at least put new lifters in there. They are easily accessible while in there and you really only want to do all this once lol. Make sure you get all the surfaces clean before reinstalling the parts and try to keep your hands off the clean surfaces
