Looks good. I like all the side by side pictures with the different gaskets. These things are so confusing for the average guy to sort out so it is nice when someone takes the time to document the process so well.

How small the bowls really are in the unported head isn't all that apparent in the pic, and the bowls in the ported heads were even more filled in.

Brad, If you look at the area on the top of the ported heads, where the pads are on the intake runners, you can see all the indications of the core shift....... The head bolt hole, valve cover bolt hole, head bolt recess next to the ports, etc.
It was just as bad, maybe worse, in the bowls of those heads.
Maybe you could get a pic of that area of the head.
You'll see the unported head doesn't have that issue.

Just compared the OOB head and the ported heads and it's REALLY easy to see the core shift characteristics you mentioned above now that I know what to look for. I can post pics later that show the difference.

Also, all 3 heads have 2011 casting dates, but the two with the core shift issues were from an earlier run.

Brad...Mine were early heads and came out pretty good. You gonna get that thing done before I head to the drag strip in the sky?? Also you have lots of good info there...

I hope you have a long life expectancy!

Seems like a lot of work for very little gain.

Brad...I never made a full recovery from that incident in 2013. On the other hand I just found my receipt for my Victor standard port heads. I bought them Jan.4th 2012.

Hey, Dwayne... forgot to ask what the warranty on the heads is.

Brad, I guarantee you won't wear out that porting

LOL, might go through a couple keyboards though.

Ouch. Lol
