454 Spark Plugs

[Desert_Eagle02]

Hey guys, sorry if this has been asked before, but I couldn't really find anything. I'm going to do a basic tune up on my 454 and pulled a plug out. Definitely can use new ones, anyway the plugs in it are NGK V-Power UR4. I've never owned a big block before, but that seems like quite a hot plug. The engine isn't a built hotrod, but it has a high rise intake and an Edelbrock 750 carb. Sounds like there may be a mild cam in it too. Nothing crazy. So should I replace the plugs with the same or go with a slightly colder plug?
