Adjusting 1.6 Rolling tip Rocker Arms?
If these are bolt down (ONLY a hex head showing) rockers, they are hydraulic, torque them to 20-25ft/lbs on the bottom of the lobe.
I really can't see installing a solid cam with only roller tip rocker arms. Normally it's done with full roller rockers.
Do some research, but I don't think solid lifters squirt oil out the push rod like a hydraulic lifter does, hence the term solid lifter. I would then turn to Comp Cams or Crane Cams for instructions of how to set your rocker arms, hydraulic or solid.
