1970 heads..pushrods solid or with holes?

My 1975 heads had solid pushrods and solid disc lifters.
I put 1970 heads on with hughes lifters (lifters have oil hole).
As far as i csn tell 70 heads had push rods with no oil hole. From what i've read my combo (lifter w/hole and no hole pushrod) should work.
I want to confirm which pushrods i should use.
