putting 305 heads on a 350 will work.you have to chamfer the edges on the combustion chambers because the 305 has a smaller bore.If you leave the sharp edges you will have bad engine knocking,probably causing damage.You will probably increase compression ratio by about a point or so doing this swap also.The 305 has smaller valves and passages which is good for torque,but engine will probably not make good power above 5000 rpm.This engine would probably do well in a pickup truck,or daily driver worried more about good gas mileage instead of performance.350 heads will not work on 305 though,305 bore too small for big valves.
