Default Help identifying ports on lsa

I have been combing through old threads on here. They have been very helpful getting my wastegate solenoid plumbed correctly. Also, identifying certain ports that can be capped off. However, almost every picture and thread doesn't show these ports on my lsa. What are they? What did they do?
Fyi, this engine was bought new from Seven Marine at auction when they closed up shop.

Is this a Seven Marine engine?
How much HP, 627?
I see that you have a thick brick with spacer and it is painted silver.
Those ports are for bleeding air out of the brick but for some strange reason they them in the bottom of the brick.
I do have some pictures of this.

Cheers

The whole engine was painted this color. It actually looks pretty good. Here is a link that I believe this engine is?

I didn't get the accessories (couldn't use them anyway or the ecm). Bought an F body pan and here we are.
So, after bleeding the brick, i just block these off somehow?

No, don't block them of,route them to your expansion tank with thin lines or hoses.
I bought a GMPP harness and a Camaro 2012 E67.
I also removed the over size brick as i could not close the hood so just now i don't have any.............
