on my first motor i used the front and back gaskets and to make a long story short it caused me to blow my motor. hydrolocked the 3rd cylinder... anyway on my second motor i usded rtv on the front and back and had no problems. i think edelbrock says it because they have to otherwise people would say then why do they have it in the set. or if someone didnt use then and not enough rtv and caused another problem... they would just say edelbrock told me not to use it and then they would be liable. so who knows. just do whatever you think works best. ask more people who have installed your intake and get there opinion.
