Hello! Does amybody know where i might be able to find or have for sale an F20c cylinder head? I am located in Killeeen, TX about 3 hours south of Dallas. Also, can you use an f22c head on an f20c block if i use the valvetrain out of an f20c head? Any help would be great as i am in the military and will soon ETS (basically getting out soon) and am on a budget. Thank You!
