I have a KB wedge block that was not drilled for lifter oiling ( my old heads were B1's and they oiled through the block )

My new heads take pushrod oiling so I had to modify the block to oil the lifters .
(no one in my area wanted to guarantee or try to do a interrupted drill through the lifter bores so I did it this way )

I have crane ultra pro lifters and I indexed the oil hole on the base circle .
The oil hole will see .100" of additional movement before the hole is closed off .

How much should I restrict the distribution block ? or maybe I should not ?
