[Roadsters] Cylinder head

[Bubba]

I don't know, but I have about 150 shop manuals from my many years as a fully
licensed mechanic, and the engineers that designed the engines and wrote those
manuals seem to mention with some regularity to loosen them as I suggest, in
sequence.

But who am I to say.  I guess opinions are better than my years of training,
schooling, licensing and working as a mechanic?

All those years I've been doing it wrong!

I'll not bother to share my wasted years of knowledge again.  I'm sure others
know better.  Happy fixing.  Good Luck.

But then again I only scored 89% on the Government exam for my license.

Oh yeah, step 13 might be of some interest

    I'm sure there are people out there smarter than me, but my opinion is as
    follows:

    It makes no difference how one loosens the head bolts.  I am sure that
many
    heads have proven to be warped after the heads bolts are loosened, and the
    head is removed.  But, I believe the condition is the result of stresses
    induced in the head by improper cooling or other factors, and that it
makes
    no differences how the "tension" is released.  When the head and block are
    cool, there is no force I am aware of which could result in warpage,
unless
    the head is already under differential stress "contained" by the clamping
    force of the head bolts.

  It might not make any difference but it can't hurt either.
