Can't remember off hand, it's posted somewhere around...but I'll grab my tune up manual or my Sun sheets and check!

L89 is the same procedures...

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.

Interesting, my old Chevrolet service manual calls for 22/24 lash on an L88...
