This head is a Marnal cast and is non jet valve. It includes springs, valves, lifters, and a TEP Cam. Not sure the specs on the cam but I do know it is a bit more aggressive. The head itself has very little use on it with ZERO issues. No cracks, pitting, etc. Will bolt right up to replace stock head and also of course eliminate the reliability problems of jet valves. Any questions please feel free to ask. Asking $680 OBO http://i39.photobucket.com/albums/e161/steve7672/638f213a.jpg http://i39.photobucket.com/albums/e161/steve7672/2cf390c2.jpg http://i39.photobucket.com/albums/e161/steve7672/dfa0f36d.jpg
