Toluene Dart - '73 swinger

How are the new heads working?
They're working. DA went up.. and the car went quicker. lol.
I do keep hearing a slight ticking and it sounds like the rockers, I know solid rollers have a little noise. But i've pulled the valve covers over a dozen times to check the rockers and lash and everything seems fine. Maybe I finally punched a hole in my headers.
