Ok, first what rocker arm set up are you using? if its the stock set up its fairly easy. If your using aftermarket roller rockers and guide plates it gets more complicated.
You can have the intake on, its just harder to see the lifters. You still can spin the push rods at the top. You most likely wont hurt the heads, worst case I have ever seen was someone who over tightend the rockers bent the push rods.
My first suggestion is to get a good service manual. That will walk you threw the procedure depending on which year and style rockers and lifters you have.
I have all 3 of the service manuals, but no way to scan them for you.
Its a 3 step procedure, you'll need a torqe wrench to be accurate.
A basic over view for stock positive stop type mounting stud, mark 3 spots on the crank pully #1 is tdc(if you look at it like a clock, #1 is 12, #2 is 6, #3 is 3). Starting on tdc, tighten( torqe spec is 18-20ft lbs) cyl 1,7,8 intake rockers, 1,5,4 exhast rockers.
rotate 180 degrees to the second mark, tighten 5,4 intake, 2,6 exhast.
rotate to mark #3, tighten 2,3,6 intake, 3,7,8 exhast.
This is from a chiltons manual for 1970 and up 302 with positive stop rockers.
If your using the roller type rockers the adjustment is completly diffrent and I cant type all of the procedure down. Its just something I would have to show you how to do. Most rocker kits come with explicet instructions.
Be sure to have soaked the lifters in oil before putting them in, and a dab of assembly lube on the rocker contact points before final assembly.
