If i get these for my e99 7.3l will they come with new boots, if not will the factory ones stretch over? Also does it come with a new gasket?

Part looks good and fit great on my 97 F350. Be sure to spend some extra money on the Ford TA-31 RTV instead of cheaper part store stuff. I followed set times and still had to re-do it after my boost leak test blew out the cheaper stuff. Not the simplest install as you do have to pull the turbo to PROPERLY clean the mating surface on the head and you have to disconnect the oil lines and one fuel line but if you have a boost leak at the plenums it�s what needs to be done. Glad full force offers a product that�s not $400 like some others have.
