I was wondering if there is a specific sequence for tightening the head
bolts on a 67 327. If it makes a difference they are not aluminum. I
have looked on the web but have not had any luck.

Thanks

Matt

There is a specific pattern listed in the factory shop manual, but I'm not
quite good enough at ASCII art to show you here. Actually I usually don't
look at the book myself anyway. I just start in the middle and work my way
in a circular pattern towards both ends, which is pretty much what the
specified pattern is anyway. Also, I usually make three passes with the
torque wrench at 35, 50, & 65 ft.lbs. I've been doing it that way for years
and havn't had one fail yet. - Gary

Yes, there is a sequence to the tightening of the head bolts. The
most convienient way to do it is to go out and get yourself a Chiltons
automotive book or a book that deals with rebuilding a small block
Chevy specifically.

Scroll down to the Small Block V8 sequence in figure 2. Follow it
religiously.
