: Is the a non - 4.0L H.O. head? Taso Stambolis 11-06-2002, 06:58 PM Its from a pre H.O. 4.0L ya? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1872094314 http://home.attbi.com/~zachr/ebays/head2.jpg http://home.attbi.com/~zachr/ebays/head1.jpg Slagburn 11-06-2002, 09:37 PM I am going to say that is pre-HO. Don't know for 100% but I think the HO's intake ports sit higher than that. And it looks like the old style thermostat housing, but they all interchange. It might be a 7120 which is the 91-96ish HO, see if he'll tell you. Jaffer 11-07-2002, 07:22 AM I't's a non-HO for the earlier Renix injection. The 1991+ HO MPI version has the intake ports higher than the exhaust ports. http://monsterslayer.com/jeep/40Head/image2.jpg For more details, see ... http://monsterslayer.com/jeep/40Head/40Head.htm | |
