    Your compression wil be around 9.8:1 depending on whether you have the block decked or not. So, yes they will work
    Objects in my rear view mirror are a good thing unless,.... they have red and blue lights flashing.

    I have the same setup in my formula. You will have no problems, as long as your block & heads have not been decked too much.
