First time poster, enjoy all the great info here. My situation: My 2001 XJ overheated due to sveral issues least of which was a bad impeller on the water pump. Have fixed the cooling issues but they caused a blown head gasket and a cracked head (0331 casting). Reading posts on this site has caused me to think that a 7120 head might be the way to go, no inherient cracking problem, better exhaust flow. Since the 2001 exhaust manifold had smaller exhaust ports (matching the 0331 head) so that the 7120 head will not match the ports, I thought that going to an earlier year header might be the way to go. Looking at getting an APN Header (http://www.ineedparts.com/index.php?target=products&product_id=15343)
with my rebuilt 7120 head.
Question is if I would have any problems with this from an istallation standpoint with the engine in the car and if there is an issue bolting the new manifold to the stock 2001 collector/exhaust system? I know about the coil pack mounting fab and do not consider that a problem. Anything else I should take into account? If I decided not to go this route, and went with a replacement 0331 head, how can I be assured that it is from 2002 or older (change in casting to correct cracking)?
Thanks in advance for your help!!
