    I do not think they will work. I think the valve will hit the bore? I could be wrong.

    no i dont think the valves will hit, but it will def drop the CR, might not be a bad deal for a turbo build.

    I'm working on a set of small valve 317s. I have to pick them up and get them to my head guy to port the runner, install a new valve seat, and flow them at a 1.89" intake I'm thinking around 260-280cfm @ .550

    Plus the 10cc gain in chamber volume I estimate to drop it to around 8.4:1
