Flathead Heads 9.95K viewsJanuary 17, 2017 0 Jim Gordon January 16, 2017 0 Comments Hi, Are your flathead heads cast with a dome for the piston or is that machined later ? Its just that I want to run flat top pistons and buy a set of heads that have no dome . Thanks Jim. 0 Answers ActiveVotedNewestOldest Register or Login Offenhauser Sales Corp, 5300 Alhambra Avenue, Los Angeles, CA 90032 Phone: (323) 225-1307
