I had posted a while back about porting 305 heads that I had bought. I did not look at the heads carfully and I just found out they came out of a 350 caprice police car. I was wondering what I have to do to these heads to work well with my 305? I kmow for sure I have to have them shaved down to reduce the 64cc and I will do a mild port job on them too but will these heads work well with my lo3?

I can say they will work better than what you got. See if they have 1.94 valves if so you are ok. NO BIGGER! And yes have them milled down. The TBI heads are pitiful in a bad way.
