How do you successfully install intake/exhaust gasket?

Ok my intake/exhaust gasket was leaking vacuum on my 65 Valiant 170. So I decided to replace it. I took everything off replaced the gasket and now it sounds like a tractor. No more vacuum leaks or sucking in air when I spray around the manifold but it's louder. So something is misaligned or broken. I know you have to put those triangle washers on the right place so the manifold can shift with heat. But it's almost impossible to do the ones on the bottom. I looked on allpar and slant six.org but I need a clear illustration of the arrangement the bottom triangle washers go. Anyone have a better illustration?
