The vette L98 heads are 58cc, not 53 (stock heads on your 305 are 58cc). If you can score a set for cheap, there is no reason not to use them. They are a much better design than the heads you have, and they will retain your stock compression ratio. The regular L98s or vortechs would cause a slight drop in your compression ratio (they are a 64cc chamber), which would offset some of the power gain that you would see from adding the better heads.
What cam do you have for the 305?
