Pushrods adjustment
I just did a 107 kit on my SGS and it's got a small oil leak. In trying to track down the leak I collapsed my pushrod tubes to check the o-rings. I decided to check the pushrods while I was in there and found I can't turn the front exhaust. My question is is this normal? I know in the original install I adjusted lash and waited until I could turn the pushrod before putting the tubes back together. Are they just supposed to spin on the base circle or any time they've had enough time to bleed down?

If that one lifter was on a cam lobe the valve should be open and there would be no way you could spin the pushrods with your fingers even if it bled down which it will under load.
Most likely it on the bar circle and the lifter bled down which would make if normal.
Real question here is do you have a noisy valve train? If not leave it alone.....

A super fail-safe way, is to adjust the individual valve, one at a time.
IE; When the r/ex is all the way up, the f/ex has to be all the way down, and that, is then adjusted.
If wanted, a 1" dial indicator can be used to witness full lobe lift on the opposite valve, but is really not needed.
Repeat the process until all are done, only rotating the engine after you can spin the pushrod, loading the lifter to .140".
