valve lash theory

[JUNAID786]

Ok so all you solid lifter guys out there. What can be done with valve lash to alter performance? The cold specs for the m110 are 0.10mm intake and 0.25mm exhaust. I was thinking of increasing the intake lash to 0.15mm to allow the valves to seat better and cool( supercharger) and to reduce the exhaust valve lash to 0.15mm to quieten down the valves and increase the exhaust duration a tiny amount. My exhaust is not restrictive at all. Will this affect the overlap?
