so ta had solid cam ?

No. Only hydraulics, but adjustable rocker arms because of intended race usage.

Just wondering if they where good head
Sounds like other than slightly lower compression they will be fine

Nothing wrong with the factory head. You must consider the cfm potential and the maximum lift that it occurs at. Schneider or Racer Brown will optimize your combinations potential.

I run Ross -10cc domes with oem 308 castings. Crisp throttle response and the neighbors love it!
