I'm no 12 valve expert but I'll give it a shot. You'll have to do more then that to make you tranny last boosted 4x4 launches. A 62 or 64 turbo, big injectors, delivery valves and maybe valve springs?

 

You're tranny has too much wear at 170k. The valve body alone isn't going to hold any power. You need to step up and get a complete trans. 4wd launches you're gonna need billet shafts too or you'll break.

For power, DDP4's are great, and a 62/12 or 62/13 turbo.
I would put a plate back in, like a #5. I've tested the no plate thing on a few trucks on the dyno, and power went down on all. The trucks all seemed to make the most power with a plate installed 3/4 of the way forward.
That's easy high 13's
