Thanks: Here are the answers I have got.

DOES ANYONE REMEMBER THE WEB SITE THAT SPECIALIZES IN THESE GASKETS?
(too many saved links to find it right now)

Paul again:
You can do all the normal calculations to figure compression.

Harlan Jillson gave this information in a mail:
Jon,
I'm not sure how much you want to reduce your compression ratio, but
you'll increase the volumn about 5 cc for every 1 mm increase in head gasket
thickness, so an increase of .040" over stock will increase the volumn by 5
cc, which will reduce your compression ratio by about 1. In other words
you'd go from 10:1 down to 9:1, that of course is approximate, and it
depends on where you're starting from, if you've got 12:1 now, the reduction
would be a little more ( about 10.6:1) and if you were at 9:1 it would be a
little less that 1 point.
I believe the standard compressed head gasket thickness is about .040",
and you don't need to worry about the bore increase, the standard gasket
will accomodate it.
