I just got my block back from the machine shop from being sleeved. they gave me 4 dowel pins that came out of it 2 which line the transmission and block up, but the other 2 I have no idea where they go. Also how do you get them back in they don't just slide in do I have to press them in or what?

 

wrong section to post this, but post pictures of the pins...

 

The other two probably go on top to align the cylinder head
