Just Bought ET-65 For My Peavey Encore 65....Ohm Problem?

Hi,

I have Peavey Encore 65.  On the input jack it says "4 ohm minimum - speakers 65 watts".  Several YouTube posts rave about the  Eminence Governer,  the lowest ohm rating they have is 8 ohm.   I decided to order a ET-65. I did order from Musicians Friend and chose the 8 ohm version ( the did not offer a 4 ohm).  Will this cause any kind of problem?  I really appreciate any advice.  Thanks!
