302 heads on a 360?

Your cam choice would be dependant on your final compression ratio, the ammount of work done to your heads, to a certain extent, and your rear end gear ratio. The choice of a compatible torque converter, if you're going auto tranny, would also figure into the equation. Remember that the bigger you go with the cam, the more compression it will bleed off, and if you're also running a stock type torque converter and highway type rear gears, then a big cam will kill any bottom end torque you might have gained by going to the 302 heads. One thought that might help in your final decision making is to build torque into your engine and make horsepower with the heads. Hope this helps.
