Engine HELP!!!!

[brewie212]

Hey guys, wondering if anyone could be so kind as to guide me though a little nut tightening procedures. I have a 73 bronco that I pulled the 302 out of and tore down to the block to clean and rebuild. My problem is that things seem to come apart easier then they go back together. I need help with tightening the rocker arms down. I have read so many different things. That I should tighten them in the firing order, I have heard that I should just torque them down to 25lbs and call it a day. One guy I talked to scared the poo out of me and told me if I do it wrong I can destroy the heads. I don't want to do that. I am just a rookie trying to get some advice from you vets. Can any of you help? Thanks guys. Oh, just for shits and giggles, I have all the push rods in their original positions and I have the timing set to the TC on the harmonic balancer. The only thing is that I have already reinstalled my manifold. Do I need to remove it to see were the lifters are? I just really dont want to have to tell my wife that I have to spend a g on new heads.
