Cylinder #1 no compression

After you have the head fixed. I would use some modeling clay on top of your piston, reinstall the head, install the push rods and rockers and turn it over by hand to measure how much valve to piston clearance you have. I do this without head gaskets and then add the comp. gasket thickness to your figures to see where your at clearance wise. You want at least .080 intake .100 on the exhaust.
