The next step I took was removing the cylinder head, which was attached by 12 nuts two of which were close to the spark plugs (I removed all four spark plugs as well).  After removing all of the nuts I bumped the bottom of the cylinder head with a rubber mallet and then lifted it off, and then removed the cylinder head gasket.  Once removed, the pistons looked very dirty, Whats next?  Here are some pictures let me know what the condition of everything looks like to you?  the cylinder studs looked a little rusty? (I think the Cylinders are numbered from 1-4 from left to right, Correct me if I'm wrong.  So that makes the pictures below cylinder numbers 4,3,2,1 from top to bottom)
