Like Gman said.. the F486 head.. is the flat head.. it is the head that was used on the Unstyled G's.. The compression is going to depend on what tractor, block and pistons you have in your tractor... If it is an unstyled G, that is the correct head for an unstyled G block. (the unstlyed G block is 1 in longer than the styled block.) If the flat head is installed on a Styled G with the Styled G block the compression will be increased.. How high the compression, will depend on the style of pistons in the tractor. Flat pistons, with the flat head on a Styled G, pump gas.. Flat head and high compression pistons.. 100+ octane fuel or LP... Good luck
