Considering pulling engine, what work should I do?

[rklingsten]

Hi folks, I've got an 01 Sequoia with 85000 miles... I've got a cracked exhaust manifold, I believe on the drivers side. I've tried and tried to get these things off to replace them with aftermarket headers but it's just not going (penetrating oil, my super-high torque gun, heat, etc.etc.) I'm afraid I'm going to bust a stud in the block and ALL the manifold nuts are on like that - mad tight and corroded, etc.

So, I've got extra vehicles to drive and I'm on the Ninja for the summer, I'm considering pulling the engine to do the headers. And since I'd have it out, I figured I'd replace the timing belt and water pump?

What else should I consider replacing while I've got the thing out? I have no mechanical issues other than the exhaust leak, this truck has been fantastic.

thanks for any advice!
