Can internal links be considered spam?

[Gracia]

I manage a site that has good page rank sitewide. My trouble is getting the correct page to display in Google for a given search. Currently, if the Google search "blue widgets" is performed I get an individual "blue widget" product page in the results, not my preferred "blue widgets" product -group- page.
I'm wondering if I make all references to "blue widgets", sitewide, be links back to the "blue widgets" product group page, the one I want Google to show, would that be ok? Would Google look at it as spam? We have about 800 pages indexed by Google, I would imagine 50 relate to "blue widgets", each having probably have 5-10 "blue widgets" references in their body that we could make links.

I did a fair amount of searching before posting this Q. Most of the info pertains to getting too many inbound links, whereas I'm referring to internal links on our site.

Thanks for any advice!
