Message	like some solid advice from members that have done this before. I have two manuals to guide me thru this "a 1990 and a 1991". I have heard there were some corrections made in the early edition of the 90. I am not new to the Z and have build a dozen or so motors but this will be my first attempt at any head work. This set of heads have a few bent valves according to my leak down test results. Will the bent valves be easily noticed with the naked eye ? src="http://i843.photobucket.com/albums/zz353/ pjzaner/ 316739_263940060307748_100000752671324_683763_ 418577505_n1.jpg" border="0" alt="Photobucket">

Thanks. - z32z 15:45:10 07/30/15 Why not have the machine shop measure the valves? - zellamay 14:28:43 07/30/15 Lap valves - EngineerLV 21:05:31 07/30/15 Not necessarily true - ZXoltan 06:13:25 07/31/15
