Nice! You stepping up injectors too?
You user name perfectly describes your position on head/ block prep....
On any of your graphite gasket motors you can almost get away with a bench grinder to surface the heads.....on a mls... no power tools should be allowed anywhere near it!
Ever read a Ford service manual, or do a set of gaskets on a 6ohh Outlaw?

Next 6 leaker I do I will remember to bust out the belt sander.
Ive never done anything more than scrape the surface very well. My 95 eclipse the first set I popped dad made me use emery cloth on it. That stuff, I rubbed and rubbed and it barely changed anything. The next set I scraped and they were fine to 30psi of boost.

how bout check the compression on the motors that you get to pick from and start there.... then no need to take heads off and do studs one at a time if compression is good.

They are the same
Thats a good start , op I would suggest that you pull the pan off the engine (s) you entend to use, if they are forged then great but imo rods arent gonna be your biggest problem,
You need to look at the main web casting rise, your previous 485hp build probably is showing signs of block flexing( main cap mating surface looks likes its been hammering against the engine block) . I know this becisue I cracked a block at a mear 430hp. Had over an 1/8" of main web rise. Cracks followed the webs from cap to cam journel('S)....
My suggestion to you is to find one with minimal rise and then have it deburred/ground down before anything.
I know a few years back swamps was having an issue finding engines to use for builds because if this problem. I was gonna build mine with them an they told me 1 in 3 7.3s they csme across was junk beause the casting rise......
Food for thought

the factory surface of the block at the time the heads were laid on it was Clean, Dry, BARE metal.

Suit yourselves boys, I really don't give a ****, I was just trying to help.
after 40 years of building, racing, and hot rodding truck engines, there's not much anybody can tell me about assembling engines .....been there, got the tee shirt.

Not saying your wrong by any means, clean dry an bare is what everyones after. Theres just more than one way to skin a cat... brake clean wire wheel an rags is just about all you need for this application. The new engines that use mls gaskets need a little differnt touch but thats not the case here
