i am putting on some new heads and am wondering what my old heads would be worth. i dont remember the casting numbers, but when i ran them they said that they were for a 73 sb400. 74cc chamber. 202 int valves. 160 (i think) ext valves. i took them apart 8500 miles ago and had the one bad valve seat re ground and put new seals in them. what do you think?

question 2. would 400 heads work on a 350? the gasket would cover the steam hole and seal that up, so they should be fine, right?

thanks for the input
