valve lash question

[Jake_Robbins86]

I've been setting my valves on a solid cam/roller rockers, the same
on the intake and exaust @ .022, it's my understanding the engine
will perform better with a .002 difference,question is, which should be
tighter? intake or exuast? used to know but forgot, thanks in advance

Since the exhaust valves get hotter they expand more, and therefore require a little larger gap.

Hope this helps and good luck, Mike

how that goes..

thanks, racin 90,,,thats good info, my car has always ran a tadd warmer
than i like, espacially when I run it hard in feature, if this could cool me
down at all, it will be worth the change,, I'm going to set them tonite
@ .022 ex. and .020 in. let you know in a couple weeks how it does,
taking this week off as bad as I hate to,,,,,family Reunion.
