Someone will no doubt come along with that thread.
For sure you will need to change push rod length; so an adjustable pushrod will be needed to determine proper length.
What RRs did you get; full roller?
Wow, that's going to give you a nice effective cam!

Thanks for the reply 65Z01, I have the Hotcam with GM 1.6RR and would like to give the cam alittle more lift. From what I remember reading is that the 1.7's increased the torque across the rpm band....

If your heads are modified to utilize the additional lift and the springs can accomodate it, then you may see similar results. You can do a search for Nathan Plemons and you should find it. I am pretty sure it was here in the C4 Tech section.

Well they will give you 6% more lift and 2deg more duration over the 1.6RRs.
Usually more duration tends to cost a little low end torque (more overlap) unless CR is increased to offset it. But I don't think you will notice the 2% down low though you might see the top end gain on a time slip.
