Mike's XS Big Bore Kit

[Spockwerks]

I have a big bore kit from Mike's, got it a year or two ago. In the catalog material they show a diagram of the piston with two oil drillways from the oil ring land to the underside of the piston crown where they emerge as jets squirting lubricant on the wristpin area.
But a look at the pistons yields...No Jets!?
Now I see they are offering to drill those passageways as a MODIFICATION?
Any thoughts?

Dang! Sounds... odd.
Here's a pic of the kit from Heiden Tuning - it indeed indicates the oil channel. With as long as this has been around, I thought this was pretty well figured out? Hopefully someone more knowledgeable will chime in. I'm thinking of doing this soon; would be nice to get this figured out.
