I went down on Thursday to check on the welding and to my surprise it was done, $75. I picked it up and drove it over to the machine shop where it was dropped off with Dan. He was going to clean it and pressure test then let me know if it was good.
I went home and by the time I got there the call was in and it tested good. So I called back and we discussed what to do. I then packed the new valves, valve guides and valve guide seals on my bike and took them down to Santa Cruz Auto. I decided to replace the valve guides even if the old ones were still good just so I would have that comfort of knowing the bits are all new. To my surprise he said it might be done later that day or on Friday. I was surprised because nothing has gone quickly with this project. A lot depended on having the right exhaust seats.
So late Thursday afternoon and no call, OK tomorrow.........Friday comes and around 10am Dan calls and he's waiting on exhaust valve seats to come in and it will be done by 10am on Sat. Yay!
Saturday(today) around 8:30am he calls it's done! I finish breakfast and hop in the 88 and drive down and pick it up($565). On the way home I thought my friend Brett would like to see it so I stopped by. That's when we took a good look at it. For me less than stellar results as we found 2 cracks.
So leaving Brett's I went to my daughters house to get a second opinion from her husband. He agreed with me and now I'm going to take it back to the machine shop on Monday and discuss the issues.
Here's some pics;

ARRGH!!!!!!!!!!!!!
I don't know but too me anything cracked in the combustion chamber needs to be fixed or I'm asking for problems down the road.
So I took the time this afternoon to check which head gasket to use. To do this you have to find the TDC of each piston and measure the distance in height between the top of the piston and the top of the block. Then pick the appropriate gasket from the chart. Mine is still for the 2 hole gasket.

Here it is Monday morning and I talked with the machinist. He did see the cracks and his estimation is that they won't be of any concern. I'm thinking he's probably right and the engine will (hopefully) outlive me. Since it is raining I will wait until tomorrow to put the head on.
