blown head gasket

[Welts12786]

i have a blown head gasket on a 77 620 l20b engine. i just need to know the torque for the new gasket or better yet if anyone has any links to a walk through video. i feel like im going to stump myself when i get to the timing chain. wish me luck just waiting on that damn special order.

Start with the middle two bolts.then the two behind the middle.Then the two in front of the middle.Then the back two.then the front two.

I torque to 70 foot lbs. but I think the book say like 40-60.

You need to do it in 4 steps.

So 1st torque is to 15lbs2nd to 30lbs3rd to 504th to final torque.

Make sure the washers are on all head bolts.

You should also re torque about once a year. Use oil or some type of lube on the bolts too.
