tappets

recently i bought repop knuckle inlet tappets.Comparing them to the genuine exh tappets there is a small hole on top of the shoulder and also in the bottom,so an open connection!
Recent troubles with another engine learned me that keeping vacuum in the system from the breathervalve thru the pushrodcovers and into the valvecovers is important in order to retract oil out of the covers.
Also i know that the inletvalve covers have both a small hole which is original.
But : why these holes in the inlet tappets? is it original?, it breaks the vacuum between the rodcovers and the camchest,and for draining oil the tappetblocks are provided with holes! It seems in contradiction with the vacuum story,and if not original i think its important to plug them off.

Hey Rein,
Do Not Use those until you have plugged the hole. Tap the holes and Loctite small Allen
screws inthere.
They have probably used the same top part
as for XL when they made them.
We´ve run into the same problem.
