Yeah I got that.
Machine shop suggested a wall clearance of 0.0035" due to my power goals so I went with that.
The second ring usually has a hook or sharp edge on it. The hook always faces down. Any mark on a ring such as a letter or a dot usually faces up. When in doubt call the manufacturer. They must go in the right direction or it will smoke like a chimney
Ill be calling JE tomorrow looks like!
Stuck some new glyco bearings in my eagles today. Waiting on a assload of parts to get here and I can really get to assembling this POS. First engine build under way :O #Learningonthejob

So according to JE spec sheet my gap should he 0.017" top ring and 0.018" second ring. Those gaps seem pretty tight to me, should I go with that or open them up a bit more?
This ^^
Also go buy a fine nail file. After cutting the rings, take a file gently to it. Also remember to only file one side of the ring.
Another note, I know they say not to touch the oil control rings, but mine were too tight. Not the center one, but the top and bottom one.
Make sure you check the gap in the bore. Take a piston, flip it over and push down the rings inside the bore to square them up. Take your time, you will start filing them slowly being scared, then you will get a feel for how much needs to come off and you will tear ass through them. First set will take the longest. 4th piston will take 1/4 of the time the first did.

Good product.
Look at the Wiseco ring compressor sleeve. You literally just push the piston in the tapered sleeve. Totally worth the money. Old school ones can crack the rings if not "just right".

I used to struggle a bit until I built this last motor. I too acquired the Wiseco sleeve and I totally agree with how easy it is to use. Like Butters said, oil up the rings/piston sides/cylinder wall/compressor sleeve and the piston slides in like a wet hooker's snatch!!
