For those old enough....or seen in reruns, there was an episode of 'The Munsters' where Eddie bet a kid at school that Herman could beat his dad at a drag race.
So Grandpa build Herman a 1/4 mile car out of a coffin and it had organ pipes for headers.
Grandpa - "this is the only car here that can play 'Oh Promise Me' in 3rd gear...."

Right before I took the block for +.5mm bore and hone, I used a fine sanding drum on the dremel and polished up the light texture left by the carbide cutters.
This is really not necessary but here is a pic of the block ready for assembly after it was bored/honed/cleaned.
All said and done, would I do another.....absolutely.
The mod is definitely worth it for a race engine.
I was in contact with Lindsey to do this for me and their price is fair, it's just that you have to account for the labor + $300 shipping the block back and forth.
That's what made me decide to do my own.

No functional reason other than I figured it couldn't hurt piston pin lube.
My pins overlap these ports by 30-40% at BDC.
If this formula 2.5L 16V @ 2300# works out like I think in class, I am immediately building a second engine, but Nikasil.
The 2nd version piston will have ports to direct oil scraper ring oil to the pins so I'd forego this middle port on that short block.

I also added ports to my last engine. I had a block from a 2.7 sitting in the garage at the time, and that had the factory windage ports. There was none between cylinders 2 and 3, but I guess you're right that it can't hurt.
BTW your ports came out a lot nicer than mine. I need a 90-degree die grinder!

if you had a long boring bar and a small bit, you could probably just drill through the back of the block, above the RMS all the way to #2 main bearing, then plug the back face.
or drill through the sides of the block and run external piping...
