All the good hemi engine builders and hemi machine shops I dealt with when I ran 426 Hemi motors in NHRA stock class set the intake valve stem to guide clearances at .0000 to maybe .0002 cold on the stock iron heads, around .0015 to .0019 on the exhaust side cold work
On the Stage V aluminum heads I would use similar clearances for a street motor, make sure the motor has some heat in it, warmed up to at least 100F + before revving it above 3500 RPM twocents
I would do a quick check of the clearances by moving the valves up and down in the guides with no springs, keeper or retainers on them first, if they slid up and down easily and no rocking side to side or forward to backwards clean I would use them and oil them up and install the seals and go racing up
No oil consumption in any of those motors shruggy
We where using stock type TRW or Speed pro 5/64 file to fit rings back then also shruggy
