I got brave and knocked the cam freeze plug off the back.

I found two lines on it:
268H-10
YAG-160

The first line almost looks like an MTS number... the 268 lines up with the MT10 intake duration. The second line doesn't look familiar... the G could be a 6.

Am I guessing right?

Should I replace the cam freeze plug with a steel one? Or brass?

Steel on the cam plug, even though I'm not sure it matters. I've never seen or used a brass one since there is oil behind it and not coolant.

My guess on the numbers, and it is a guess, is 268 duration, with a 110 LSA

Looks like a Comp cam number. 212 degrees at .050. Like an MTS #5 cam. Good smooth low speed ca woith a little extra low end torque.

I’d say that you just found out that your cam is just about perfect for your application.
