Bad Oil Test /Too Much Chromium

I just got my latest oil analysis back today , and it did not look good.
The following items significantly increased , in ppm :
Aluminum - went up to 11 from an average of 2
Chrome - went up to 54 from an average of 1.4
Iron - Up to 41 from an average of 13.6
Silicone--Up to 33 from an average of 1.8
So , needless to say , I am a little concerned about what happened to my really good running engine .

Something definitely happened in the last 7300 miles.
There are a few things that I have changed in that period.
1) Went to a slightly lighter oil for the winter
2) Switched to AFE Mega Cannon w/prefilter
3) Changed to heavier valve springs.
4) Changed the head gasket
5) Advanced the timing
6) Installed 4k GSK
7) Installed larger fuel plate
There is a possibility that I was getting dirt in through , perhaps , a leaky "filter minder" grommet . That would explain some of the readings.
But I an stumped by the chromium . What has a lot of chromium inside the engine ?
Thanks
