I'm using Hughes roller lifters and

a mechanical roller lifter is not nearly as fussy on oil as say a VVT motor
but the 10 in 10-30 is way obsolete
run 0-30 modern oil or 0-w40 if you are a corvette going to "track day" or have older larger bearing clearances
royal purple or whatever

the link in Hughes #5 (above) is broken
Hughes #8 looks good give it a careful read
