The figure this part comes from is CYLINDER BLOCK AND HEAD, T110 & TR6, so it belongs at the top end of the engine, mating to the barrel and carrying the valve gear. Since it's cataloged as complete with guides, you're not stuck sourcing and fitting those separately.

Our record ties this head to catalog appearances from 1960 to 1962. If you're matching it up to a specific engine, check your own numbers against this range before you order, since head castings changed over the years and we don't want you fitting the wrong one.
