Additional oil to lifters/cam

Since i'm installing bigfoot lifter to my wbx case, would that reduce oilflow to the cam/liftersurface.
Due to the big face of the lifters blokking the oil that comes out between the case and the lifter body?
if so , is it possible to drill small holes in the Oil galley to get an oil flow out to the lifters/cam,
How small does these holes need to be to prevent a big loss in oil pressure.?i was aiming at 4 holse pr casehalf.

Or is it possible to make "lube-a-lobe" holes in my CB lifters?
The holes is not drilled but...what's the name of that process again..?

Electrical discharge machining. that's the word ,
Thx.

No ideas regarding these holes in the case?
I know some guy's has done it to get oil to the underside of the pistons to cool them.

Or buy a set of the CBs, I believe they have a better reputation anyway, and already have the EDM'd holes...

On ALL the wbx with T1 lifters I build I do the oil squirters mod's that you discribe.
I use a 1mm drill bit and angle the drill bit at the camlobe, i only drill one side of the case(main oil gallary side), thay work great, if you presurise the main oil gallary with water you can see how great they work, with no presure loss.
good luck

What do you mean by " only drill one side of the case (main oil galley side) ?
(main oil galley is the one in the middle going from one case half to an other.. Right ?)

-Only in one case half ?
-Only one hole for the lifter near the center (main oil galley) per side.
-Only one hole per lifter
-Only one hole per lobe


Can you specify a little more please, i'm not quite sure what you mean! ?

There are so many options :lol:

Btw. Why do this mod ? It should be one big oil mist down there, isn't the lubrication sufficient !?
Maybe a stupid question because I have experience cam wear on almost every WBX I have taken apart. But does the mod make a difference ? that's the big question ...

i mean, one hole per cam lobe on one side of the case(the main oil gallary side, the oil filter side) this is to makes 100% sure oil gets to the cam lobes, not just by chance!

good luck.
