Hey guys I bought this ls1 motor from a member on here and just wanted to get some feedback from you guys. Does it look like these heads have been port and polished? I've never seen port and polished heads on an LSX before so I'm looking for a more experienced opinion. Thanks in advance guys.

 

it looks like there are some rings in the intake ports that could have been made from a CNC machine... its possible.

 

yea they have rings all the way down looks like alot of lines right

 

yes they are

 

They look to be ported but you would need to clear up the runners and take pics looking down the port to tell to what extent they have been worked.

Yes, from what i can see.

Hard to tell but looks like it.

Here are a pics of mine if it helps...
