If you are very attached to the car it is worth a shot to see what maybe can be worked out between Chevy and the dealer. Being Service Techs you probably could get great advice from your dad and brother.
Wife hates any down time on her vehicle for routine maintenance and I did recommend a fully electric for her next vehicle.

I did my plastic upper intake on my 96 Bonneville twice. GM would not cover it!
Second time made up a reduced Dia EGR pipe so it does not touch the plastic intake.
Put on metal lower intake gasket also.
Stellar 3800 engine and a cheap plastic intake IMO.
