The service manual states :
Intake . 254 mm (. 010 in)
Exhaust . 508 mm (. 020 in)
The valve lash limit according to the manual is :
Intake
. 152 mm (. 006 in) Min
. 381 mm (. 015 in Max
Exhaust
. 381 mm (. 015 in) Min
. 762 mm (. 030 in) Max
If measured valve lash falls within these specs no adjustment/reset/ is necessary. Engine operation within these ranges has no adverse affect on performance, emissions, fuel economy, or level of engine noise.
Again this is straight out of the Factory Service Manual.
