Look in the s&s link I posted. The 3rd step says .1252
but keep reading, then tells you to back them off so much etc.
The 7 and 10 flat thing, can you verify buy looking in the bores that you are indeed on the base circle of the cam on both cylinder's.
Next I'd find out s&s tolerances in their spacer's. Gonna have to do a little reverse measureing to say

Tpi per turn graft
So from my taketakeings threw the info IIm finding
Lifters w/o limiters are .200
With limiters .100
Half way would be 1 full turn for .042
Be 6 flats?? So would need 7 flats for .049
At 7 flats can you spin the push rods with your fingers fairly easy after letting them sit for 30min or so to let them bleed down

Confirm your TPI and Read the S&S instructions again... it's all there.
The only thing you need to know about the SE pushrods is the TPI. You are using S&S lifters...follow their instructions
Btw, Do your SE have 6 flats or 4? (I think it's the older ones that have 4, but just checking)

Ok this is gettin really aggravating. I adjusted my pushrods last night about 2 turns past where the valves open, just to make sure the lifters bled down properly. Now on the rear theres 12 flats between zero lash, and the valves opening. The fronts only get about 6 flats each. The plunger on the front cylinder lifters doesnt go down as far as the rears do. If I keep cranking the pushrods til the valves open, the plungers will continue to go down, but not as far as the lifters in the rear cylinder. What the ****??? Instructions dont say anything about lifters being specific to intake or exhaust (only the pushrods are). Shouldnt the pushrods require equal or close to equal adjustment? I cant believe what a ****in headache this has turned out to be. And good luck getting s&s on the phone. Thank you for any much needed help or advice.

Pulled the travel limiters out and adjusted the pushrods the 2.4 turns the instructions call for and have some kind of terrible clacking sound so Im pretty much done with this ****. Think the pushrods the dealer sold me originally bent the valves so Im ****in done.

If so, it's probably fine. Ride it bit, it will probably quiet down.
That being said, I would have probably adjusted to .125-.140 instead of .100 that SE instructions call for. And you still can later, if needed

Understand the frustration, nothing worse than chit not working right. I had a similar experience installing mine where one would adjust almost as per the destructions and the other nowhere close. Turned out in my head I was thinking to be at base circle on the front while trying to adjust the rear (which was on overlap). Total brain fart on my part. this kinda sounds similar to my problem.
My 2 cents for what its worth. Leave it for now, go drink a cold one.
Come back tomorrow calm, pull your pushrods, pull the lifters, re prime lifters and reinstall. Reinstall the rods, making sure you are on the base circle of the cam you are installing on. Adjust and let them bleed down.
A start over maybe all you need.
