Guest shuyun Posted March 13, 2003 Share Posted March 13, 2003 I have a blank E31 Head no valves just the head what parts should I put back on? I have a Camshaft but have no idea what shape it is in. Should I do the work or would I be better off having the local speed shop put it back together? Quote Link to comment Share on other sites More sharing options...

Guest shuyun Posted March 13, 2003 Share Posted March 13, 2003 Five or six hundred United States Dollars. What other head has the most interchangable parts? and what book should have this info? Thanks Quote Link to comment Share on other sites More sharing options...
Mike C Posted March 13, 2003 Share Posted March 13, 2003 A lot depends on the displacement you are planning. The E31 is too small a chamber for the flat top 2.8 motor, but would be OK on a dished one. Assuming pump gas drivability. The E31 would be excellent with big valves on a 2.4l motor. The E31 has small valves and bronze seats as well. A better choice would be to get an N42 from a 75-76 280z and just R&R it since it has hardened seats and big valves already along with the square ports.
