I would put alum heads on what ever you choose as the iron ones are heavy-----------
yes im told heads and cam are the most important part of any motor i plan on rebuilding whatever i get but i wonder since aluminum expands at a differnet rate than steel or iron what affect does this have on a motor, and can you boost iron heads more with nitrous or is it about the same strength?
