Roland;
-20 + years ago in my automotive-machinist-days we used machinists'
"DYKEM". It came both in a quicker-drying brush-on version and a
"cream-type" in a tube that dried much more slowly. The tube stuff is
what we always used for exactly what you want to do. My friend I
worked with had 4-5 different sets of heads matched to specific
manifolds that he was always changing on his bracket racer.
-Alignment works best on the engine, but if heads & manifold are off
the car you can probably do one side at a time & get real accurate
measurements.
-You'll need:
-intake gaskets, used are ok, that are white or light-colored,
preferably without writing so you can see the DYKEM better.
-a set of intake manifold bolts & another set but only about 1" long
with washers & nuts.
-Do: depending on what's easiest for you..coat the intake manifold
-to-head sealing surface (1 side) with a good layer of the slow-dry
DYKEM. IT stains, use gloves; I think Acetone is a good remover.
CAREFULLY lay the intake gasket on the manifold and screw down with
the set of shorter bolts. Let dry. Do the same for the other side.
Let dry and remove. Do the same with the heads, remembering your
top/bottom & front/rear references.
-When you're done, you'll have a gasket that on BOTH sides shows you
where you do & do not have metal. I always made 2 sets, 1 as a
"master", the other as my pattern. If my heads were already ported,
then I carefully cut out the outline of the heads in the gasket
itself. Then, when matched to the intake manifold-DYKEM side, I
scribed the outline into the DYKEM to show where I needed to remove
material on the manifold.Or, vice versa.
-Another watch it: I've seen where folks have done the EXACT steps
above, then put in ANOTHER stock set of gaskets when they put the
heads back on the car. All this work exactly matching heads to
manifold, then the gasket covers up about 1/2 of what they did!!
Make sure you match the gaskets to what you do..careful around the
water passages.
-Does this make sense? If not, call me. (408) 955-7046 wk or (510)
794-7506 hm.

Do any of you have a sure fire yet simple method of checking intake
manifold port alignment to the heads? Once in place the ports can't be
seen or reached with a scribe or marker so it'll have to be some sort
of install-uninstall-then-check method. Best suggestion I've gotten
so far is to use clay.
For reference this is a dual-plane aluminum hi-riser for my 289.
