Trick Flow heads
For others wondering what components to use:
Myself and another member here are running 1.6 Erson roller rocker assemblies w/B3E mild correction. Mike there mentioned to me that these rockers would work, as will others, but that there were better rockers for these heads. The Harland Sharp or Mancini rockers are almost perfect needing minimal correction (if wanting the geometry spot on) as told to me by him.
The rocker fasteners can be ideally studs but bolts are ok too, I used MP billet copies with the supplied Allen bolts made by Angelucci. Not one single issue installing or in running. The head bolt/studs I believe are the only required item, IIRC.
Mike has much experience with these heads and various rockers and imo would be the man for best advice on what to run.
