Are you looking for 

 plot(0,0, main= bquote(paste("Results for ", beta[3] ==.(b1))))

?

Your fundamental problem is that expressions need to be syntactically
complete, so "==.(b1)" with no left hand side gets you a syntax error.
However, you can supply a dummy, and

 plot(0,0, main= bquote(paste("Results for ", beta, 3, {} ==.(b1))))

does work (although possibly not with your desired output).
