Chevy Water Neck Bolts Leaking

Whenever I go above 6000 rpm lately, coolant has been shooting up out of my water neck like a fountain. I had a billet aluminum swivel neck with o-ring on a Super Victor intake. I added a gasket to see if that helped. Still did it. Then I switched to a basic GM aluminum water neck assuming the swivel part was the problem. Still did it. After a drive I noticed tiny bubbles forming around the bolts that hold down the neck. So, coolant is somehow leaking past the bolts. I know the holes are blind, so it must be seeping past the gasket. If so, I guess I'll try some Right Stuff sealant on another gasket and see if that does the trick. What do you all think?
