Assembly time
I am very focussed on getting the push-rod length and rocker install positioning correct - calculating the centre of the sweep and half the lift and mapping those points out on the rocker...
I use a marker on the valve tip to check the wear pattern - the spring is so light the marker hardly wears off. 
Anyway - I end up with a measurement of 6.407 (which nobody makes as a push-rod length).
Eddie from HSD had suggested I use locals Crow Cams for the push-rods as they sell in 0.05" increments
I rang Crow Cams on the Monday before the Australia Day holiday sort of expecting they'd be closed.
The price for a set of Crow's push-rods was within $10 of Comp Cams Magnum range at Summit after the exchange rate but before shipping.
Crow shipped the push-rods that day and I had them by 4:00pm - I was impressed
