416 Stroker Kit Question

OK. So it is starting to come together, somewhat. I have narrowed it down to the stroker kit from Summit (because I know someone with an account that can get a good deal). The part number for the stroker kit is 1-98013. I am also going to order the Edelbrock heads. Should I get the 60779 or the 60179 heads. I see that the difference is the CC of the combustion chamber, but I am not sure that there are no other differences and want to be sure before ordering.

Thanks
