got some spare time so i did a little port and polish work on an 08 intake manifold and some 862 heads. man these heads have a rough intake port!!!
the hole is the rocker bolt location a little teflon on the bolt keeps any leaks out
a set of l92 823 casting heads i did a while back

What kind of HP gains are you expecting from a port and polish job?
