Factory roller 360 and 308 head questions.

1.92 intake vale and a bowl hog and blend would work much better with those heads- keep the velocity up. and don't blend too much in the are next to the valve guides or you hit water - and $1000 is p-----d away.
unless you are going to spend $800-1000 for a convertor, go with the XE274, the bottom end torque will be better and very little Hp difference.
The stock mopar lifters will work too.
need anything elase - pm me.
