Where and how are you planning on breaking it in? Opinions vary wildly but mine is that the rings are set after 10 miles.

It's been a while but I think my CCP was off from the calculator as well.

I didn't put new rings in the motor.. I used the old ones at 20,000 mi... After I cleaned the cylinders and the pistons and the rings and put it back together, I put a coat of MMO on the cylinder walls and the rings... I'm guessing that might explain why the compression was so high... We'll see what happens when I get it started later on in the week..

I'm in the same camp of take the oil pump off and inspect it and re-align it on re-install. Personal experience. First time friend and I did our cams at same time together, neither of us took the oil pump off, both of us had problems. Next time I took it all apart, inspected, re-aligned, not an issue since and I've done it that way a few times now.
The problem is most likely that you didn't replace the crankcase scavenge O ring. They take a set, even the Viton ones. I replace them every time the cam cam cover is removed. FWIW I don't believe the fancy tapered pins are needed either. Simply rotate the motor back and forth while tightening the oil pump screws. Never had issues with sumping except for a 131 ci SnS cased motor but it's base issue was different.

@ 98HRFB.

Not sure why the W5.
As a 103 my 07 egc has had 4 different cams, The SnS570, W5, Syke Dickripper 2000, and W777. Motor has over 200 dyno pulls and the bottom end has never been apart. Each successive cam was an improvement on the previous cam for me.. This all occurred from about 20000 miles to 80000 miles. Heads were Syke ported and flowed, with AVnV 1.9 intake. 1.63 exhaust. I've not had any reliability issues. At 80000 it was bored to 107, currently have about 104000 on it.

Yeah Max, I don't think it really does matter ... I can't believe I was able find a 2016 post of mine (including artwork ) that referenced this (I did add a few words to make it more clear this time)

Lifter Oil hole is open to reduced diameter area (shown in green). Oil "passage" from case enters at reduced diameter area and is "sealed" at areas shown in red. Pressure makes oil find every hole (and controlled "leaks") it can

This was my thought as well.. Even with the Evo's I can remember all the chit chat about direction which is totally irrelevant... No matter where the port is if you have oil pressure it's gonna find it... Never believed in directional lifters..
