If Rising Heat of Stone and Sand has a Sacred Site in a land for targeting purposes due to "Entwined Power," do Invaders there have -1 Health from its "Blistering Heat" Special Rule?

No, the Spirits can use each other's Presence for targeting only, not for any other purpose (even in the period of targeting).
To expand on the situation, a land contains one Presence from Rising Heat of Stone and Sand, one Presence from another Spirit, and a Town with 1 Damage. "Entwined Power" is used between the two Spirits, and then Rising Heat uses a Power that requires a Sacred Site there for targeting. Even though targeting the Power is legal by "Entwined Power," the land only counts as a Sacred Site for Targeting, not for the Special Rule "Blistering Heat."
