Yes they look like that and I quess the theads are tight enough that they don't move when set. The 2 that are 3/8's must have never been adjusted when the engine was rebuilt. I did not go over the clearances when I got it back but should have and will now. I have a high lift cam in this motor and the valves were opening some but not much. I also have a set of copper head gaskets coming so Maybe I can get it back together by midweek with a little more confidence.

I appreciate your interest and advice

As for your gasket problem, you will probably have to use copper ones....T/M

I big ball of clay, or PLAY-DOH works great too. Just flatten it out over the top of the piston & roll the motor once or twice & check the thickness of the play-doh afterwards.
