06 valve adjustment

[CKelley1]

in 06 they changed the exhaust valve lash from 0. 020 to 0. 026 i thought it might be for a change in components. i just read it was to allow more time on the seat to transfer more heat from the valve. does anyone know for sure. is joe donnelly out there

I thought that was always the spec if it fell outside these parameters. My guess is your right about allowing more time on the exhaust seat, here's a link: http://www.glacierdieselpower.com/images/PDFs/CR Valve Lash Adjustment.pdf
