What heads

My 57 chevy has a 30 over 283 with about 1,500 miles on a 10 year old rebuild. It has power pack heads on it and a 4 barrel . I want to change out the heads and cam but I would like some input from other Chevy guys. I used to have a 67 el Camino with a 60 over 283 300hp heads and 350 hp cam and it ran great. But since the 70s they have improved on a lot of speed equipment. This car is a cruiser and I will be putting in a 5speed in it. I want a lot of torque. Got any Ideas?
Thanks

In the past (mainly before 1975) the way to make power was to add massive flow with a disregard for velocity. In general, modern heads (even factory castings) will give you tons more torque and horsepower without sacrificing anything. Look for heads that flow enough to support your RPM range with the smallest port volume you can find. I think you'll find that modern heads can flow much more than those old heads without sacrificing any velocity because the ports aren't much bigger. The new standard is the Vortec head, but I think the chambers would be too big for your application.

Keep in mind, too... those old 300 hp heads were based on gross hp ratings. By today's standards that means about 215 hp. Compare that to vortec heads which are capable of 350+ hp in stock form, those old heads have nothing on bone-stock castings today.
