Carl 3 Report post Posted October 23, 2006 The 731 head is for the 320 nd 323 M20 engines, the double valve sprung heads came on the 85 323i heads, 149hp as opposed to 139hp and slightly lumper, not heard of a 320i head having the double springs. Still, being a saffa import anything is possible, they've got that crazy dutch gene in them Quote Share this post Link to post Share on other sites
Hartage 0 Report post Posted October 23, 2006 That does not always follow with BMW m20's. Had a 1990 320 with the double valve springs, Jap import,auto. carl your head at my place is 85 323 head, with single springs, i think that most of the last motors, and motronic m20's had improved valve springs. Would like to know if there is a way of telling from the numbers on the heads. The 731 head is for the 320 nd 323 M20 engines, the double valve sprung heads came on the 85 323i heads, 149hp as opposed to 139hp and slightly lumper, not heard of a 320i head having the double springs.
