John,
You had left me a message about a month ago about the proper way to set the valves at the head shop and I deleted the message by accident. My mechanic &quot;Howard Flowers&quot; @ Tallahassee Truck Service needs to speak with you about the way to set the valves / seats in the head. He had his head repair shop do the work and we had it running yesterday with out the exhaust manifold on it and it is leaking around the valves on cylinders -1 &amp; 3 
I gave him your phone # and he will be calling you from (850) 576-3772 
Thanks for your help that you have provided me on this issue.
