[Mark O'Neal]

The swap off for your original question are basically as follows;

The pedestal mount rockers are technically non-adjustable. So, if you do swap your cam out, you will have to dance around with pushrod lengths to get the adjustment correct.

Also, should you intend to go to the stud mounts later, you will need to ante up for the machining to convert, although Comp does have a stud with a 5/16" mounting "bolt".

The stud mounts are adjustable, so you can adapt for reasonable changes in lift without having to re-engineer you engine.

You will also have to make sure the valves are adjusted correctly for startup...

Going to 1.7's will provide no practical increases in H/P because the "gains" all come at max lift. The lobe profile is the same, and time (duration) typically means more to you than minor changes in the window.
