E7 heads on a '73 302?

[gold73fastback]

I have a set on E7 heads collecting dust, and was thinking about porting them and putting them on my '73. I know they will bolt on, but will I have to make any modifications to the valvetrain or coolant passages?

if anyone has done this, do you have any advice?
thanks

they bolt on using stock parts. no problem. no mods.

i thought the coolent pass's are on the intake side are different and also the cc chambers are a lot bigger which would lower your compression

the coolant passages are bigger but that is no prob using the older intake you just have to use the newer intake gasket. going the other way dosnt work, can't put older heads on with a newer intake
