Hey guys, I have a 305 motor out of an 85 k5 blazer, I’m about to install a new oil pan gasket but I don’t know which comes first, the front and back rubber gaskets or the side cork gaskets

About the head, can I remove the head with out having to take off the rocker arms and push rods? I thought I could undo all the bolts and it would slip off with no trouble. am i wrong?

 

i'd use a 1 piece oil pan gasket, they cost a little more but are near bullet proof. the side gasakets tabs fit under the rubber end pieces. no idea about the rockers. you don't really need to remove them just back the nuts off enough to move the rockers out of the way for access with a socket.
