I believe that the LO5 caprice motor has a compression ratio of 9.8:1 with the stock heads.Is this correct?If this is correct,what would the compression ratio be if I added the 285 Hp heads with 64cc chambers? I am assuming the LO5 heads have larger chambers but I don't know.I am debating weather to add the 285 hp heads or not.Hope these questions make sense. thanks......bob
