Tony,
The main benefit to double gaskets is not the dual sided blue seal but the added thickness which may "smoothen out or neutralize " whatever imperfection in flatness may be the cause. The key is to properly glue the two together to ensure a good seal...using the Permatex spray.

Have you ruled out a hairline crack in the intake either in the main base, (near a corner) in a runner or the at the runner base ?? The V-jr has all four outside corners equally weighted same as the main intake supports. I recall you have a dual plane which may have extended corners. Are the outside 4 corners extended like rabbit ears requiring lesser torque than the 8 centers ? My dual plane was like that and ONE of those corners stressed thru heat cycles and held onto a hairline crack for a very long time ......not allowing a solid seal as it heated and cooled so did the corner but at a different rate than the rest of the intake. Sandy welded it for me but that only lasted one season and the hairline crack reappeared extended below the weld. In the beginning you'd have to have the intake very clean to even see the hairline crack....but trust me it threw the seal off. Could you try visually scanning it inside/out with a 3" maginfying glass ? Driver rear/passenger front......that has to be siginificant ! Are you available during this week ? Gotta put this thing to rest.
