I just had the heads redone on my 84' Z28 with the 305 H.O. Motor. The heads are on, the intake manifold is back on, I'm just waiting on my exhaust system so I can start it up.

Right now, I have the rocker arms bolted down so there is a little bit of play, you can shake them, but not far at all. My question is, will it start if they are this loose, I don't want them to be too tight.

My next question is, once the car is on, exactly what do I have to do. How long does it have to warm up, are the rocker arms going to be clanking around during the whole warm up, and is this bad for it?

This is the information I have gathered from many mechanics, and managed to put together in a way I can understand, please correct me if this is wrong:
Start it up, and let it warm up really hot, take the valve covers off, and spin the pushrod while tightening the nut, until the pushrod stops moving, then turn 1/2 turn.

Is this right, is there any special sequence of rocker arms I should do?

Pleas help me, I appreciate it.

 

I'd tighten them just untill they dont move easy. After that, fire it up and tighten them down untill that rocker stops making a ticking sound, then another 1/2 turn more.

 

tighten them down until there is no up and down play of the push rod, but you can still turn it rather easy. then you can start it, and like 427 said tighten them until theyre quiet. the factory turned them a full turn so the would last through the warranty period. only do 1/4 turn if you built a high rpm motor, otherwise 1/2 will be good
