Man when I had the 305 in my car I was using just the 1.45-1.55 gaskets and they worked great. I used to put rtv around the gaskets at the sealing surfaces and they worked a lot better.

When you swap out those gaskets be sure to check the bolts few days later for any loose ones.

Right on good advice. I forgot to mention that but definitely check the bolts. They tend to rattle loose sometimes. Escpecially if they are headers.
