what radiator to use?

got another ? for anyone that can answer. I am running the indy ez-1 heads with roller rockers and ive been told that im gonna have a hard time with valve covers fitting because they will hit the heater motor. Anyone know anything about this i want the mopar performance black wrinkle vc's but dont want to order them and they not work
