Adjust valves sbc cold

Answer 1

For hydraulic cams:

With #1 at TDC, adjust 1,2,5&7 intake and 1,3,4&8 exhaust for zero backlash plus 1/4-1/2 turn preload, then rotate engine one revolution for #6 at TDC and do the same thing with the rest of the valves.

For solid lifters follow the same procedure except use cam manufacturers backlash specification and 0 preload. If block or heads are made of aluminum, allow a few thousands extra backlash cold and recheck hot.
