OP,
since you are asking about how to adjust the valves, i can only assume you were not going to have the heads checked for flatness and cut if needed. i highly suggest you have that done when pulled or you will be right back in your same predicament within the year.
I also suggest you verify what head gasket thickness you have under the heads now and do not put anything thinner in place.
do not reuse your current head bolts
make sure your heads are pressure tested as well to check for leaks. dont be surprised if the machine shop tells you, you need valve guides and/or you need new valve seats cut. specially if they have to take quite a bit off the head to get it back flat
make sure you put the head gasket on correctly (not upside down)
when putting the rocker shaft back on, incrementally tighten down the bolts a few turns then switch to another bolt. even with the valve lash adjusters backed all the way off, they still will depress the valve due to the amount of lift the cam has.
when taking apart, back ALL the valve lash adjusters completely off till they stop
cap off all your fuel lines that are open, you dont want any trash in them
make sure you have new o-rings and seals for everything you are pulling apart. the merchant automotive kit comes pretty damn complete for the top end rebuild.
there is alot to look at and the devil is in the details. good luck and be diligent. DO NOT try to rush this
