Tufte-LaTeX uses the titlesec package to format its headings. If you
look in tufte-common.def, circa line 1611, youll find a number of
\titleformat macro calls. Those, along with \titlespacing, define the
heading styles.
You can copy and paste those commands to either your document or to a
new file named tufte-common-local.tex (which will be loaded
automatically if it exists) and modify them to achieve the desired
style.
