What roller rockers in an LQ4?

[BlueZee28]

What size RR's came in an LQ4 stock? Model year 2000 to be exact, in case GM did another one of those funky model year changes. I was told by a friend that they should be 1.7's?

My other question is, if they are 1.7's, do you think it would be safe to put the stock rr's back on the heads with a bigger cam? (Say, a TSP 228R or Torquer V.2)

They are 1.7 and yes you can use stocks on the cams you specified.
