5.7 Hemi swap on the cheap Tips and tricks inside.

They make a set for the 2010 Challenger, full length would these be a better choice? Would these be a better choice/fit? Part # 72-C2242 (ceramic coated) or plain Part # 70-2242. Jegs has them for $293.99 (plain) & dbl. for ceramic.
Cool thing is I can put the ones I have on my Ram ;-)
