do you want to convert the 302 you have? or put in a 302 boss already assembled. the heads on the boss is really the only major outside change/look of the engine. so motor mounts and things of that sort will not matter. cleveland heads,boss pistons,boss intake,boss valve covers will be major parts you will need.

the rods are also a different length

I'm pretty sure that 351C heads can be used on a "standard" 302, but the coolant passages in both the head and the block have to be modified. I think I saw that in a book called "How to hotrod your small-block Ford"

I agree with others who have posted on this topic when they suggest to go with aftermarket "bolt-on" heads. Ford Motorsports used to make some, I think.

True 69/70 BOSS 302 heads do not have to be modified or is there a need for a special intake (only the actual BOSS intake is needed-and there were several variations).

a real 302 boss bock is a 4bolt block..with a factory steal crank...and are high dollar pices...a clevland head can be made to fit..with a few drilled and plugged holes...which is called a cross boss...but unless you want to run a high rpm..the boss and clevland heads are way to big for a 302...ports are huge ..boss heads had 2.25 valves in 1969 and 2.19 in 1970..plus a boss 302 intake are hard to find..unless the aftermarket has started to make them.....than you have to have headers made to fit the car..
