Heads for a 360

What are the casting numbers? Most would probably say keep the 360 heads if they are in worthy shape. I have 318 heads only my 360 and wish I didn't out of breath at 4500-5000rpm. However, motor runs great and strong enough for the street but not strip. By fast burn I assume your talking the 302's closed chambered. Probably good for a 1/2 point in compression but not so good for breathing on the big end. The 360 heads will have the bigger ports and valves. I am sure the smart folks will chime in soon enough to help you determine your way forward.
