Re: L78 tune up
Thereabouts...if you get too tight, the thing won't wanna rev and you're putting too much stress on the valvetrain...but conversely, too loose and you'll hammer your lifters to pieces. From .022-.028 is probably the safe zone assuming it's an older stock cam...I've seen a newer replacement cam with 16/16 figure, and then of course some of the newer tight lash cams take that a step further.

Re: L78 tune up
Buizilla's right. A HOT aluminum head motor with the same camshaft would use the same valve lash as a HOT cast iron headed motor. A COLD lash setting would be different between an alum. head motor and a cast iron head motor. I too, frown upon the cold lash.
