Depending on the size of the socket you may be able to tighten the head bolts without pulling the cams, you'll just need to turn them periodically to let the socket clear. I've done it a couple times.

When you torque the head bolts down remember to do it in multiple passes and also make sure to loosen any head bolts which are not already loose by backing them off 1/4 to 1/2 turn.

Ill have to take a look at them tonight I guess. You said to re torque them to 75 ft/lbs.

Ohh I have another question. Is there a tool I need to get to install the new exhaust manifold studs to safely get them in without damaging the threads? Or should I just use the two nut method and try to torque them to 29 ft/lbs

I've only ever replaced two studs... if you're going to have problems it will be with the threads themselves. Do your best to get the studs seated as well as possible, but don't worry about torquing the studs by themselves.

Ok cool that makes me a little more at ease. I was just woundering because the onesthat were on there either backed them selves out of the head or were not seateds properly

If they haven't backed out and the gasket hasn't disintegrated then you may have a problem. When the studs pull free (which, sadly, isn't too uncommon) it's the threads in the head which go... not the studs. It'd be great if it were simply a matter of replacing the studs as with the head you have to drill and install helicoils.

luckely only one came out with the threads i think. i looked ast them and i ran another stud through it to see if the threads were still going to work and it tightened right in maybe i wont have to drill. whats your opinion on this matter. only one didn't come out with the nut and its the one that looks like it striped out a bit on the inside all the others are good and intact

WOOOT i should get most of my parts tomorrow from toyota

oh and the gasket was pretty decenigrated/melted on the side that was really loose
