I have a extra set of brodix -12s ported by weldtech (sprint car heads) and I am currently building a motor for my dragster. Some people have told me that these heads will crack on a blower motor. Anyone have an opinion on this?

 

call brodix....i highly doubt it though. All of brodix heads have thick decks. Those type of heads are usually in sprint cars with giant compression running on alcohol

 

yea they came off a 15:1 406 making 850 horses but the supercharged motor should be making around 1600 horsepower
