Trick Flow and Ersons?

I installed my TFS heads and Comp Ultra Gold rockers without modification.  I checked the contact of the roller to the valve stem through the entire range of motion and all looked well.  I did end up running a valve cover spacer to get rocker arm clearance, but I'm also running stock chrome Powered By Ford valve covers as well.

Granted, I'm not running a ton of lift, but should I be looking at something else?

What did the pattern look like?

What's a good method to check the pattern?

The engine is back out of the car, I'll check it before I tear it apart.
