So, does it need a little dab of silicone or a new, more compliant, boot? Or a 500 Fanatic AL intake? 
A lite coat of fuel resistant sealer on both sides of the gaskets will usually fix a problem like Rider414 shows in his picture.
The picture with the leak is with brand new gaskets and it leaked! I seemed to remember guys telling me to use the semi-harding sealer like you would for the case halves. It spreads easy. After sealing it, it held like a champ. The new motor I went a sealed it up also. The lesson I learned is that even with new gaskets, there could be leaks.
