Well,what makes a 350 and a 400 different is the bore size,stroke is the same,also,about switching heads,know what you have first,by putting heads off a bigger motor you may end up loosing power by dropping the compression due to a larger chamber size. As mentioned,6x heads are good,rectangle port 400 ram air heads are real good,but you need the matching intake,and they are hard to find,edelbrock makes a set that are aluminum that are similar,like the super duty ports. The biggest things Ive seen for the ponts is the cam and headers,next would be intake and heads for me,oh yea,and a 4 bolt 455 would be on my hunt list also.
