I did the same recently. I made extended length links by using 7/16 b7 (grade 5 threaded rod) matches the height of the torsion twisted front end. I think I used 12" pieces. Used metal lock nuts and put red loctite on one to act like a bolt so I could tighten the nut on the other end.
The balance shaft was used after 03, I know mine has it. I'd also suggest the PCV bypass where you use a breather instead of sucking it through the intake
