I used a 10 pc Wintools xzn triple square kit off Amzn. Worked pretty much fine when I pulled my head last year. Removing the rocker arm assemblies and cam stuff helps.

Might consider using a cheater bar on a cheater bar. I put a metal pipe over my 3/8” breaker. Then again, ya could just use an impact gun.... Drop me a line if ya need me to walk ya through it. That nut/bolt on the turbo to block bracket is stupidly difficult to access. Hope your ride is on a lift!
