Overheated - HG for sure

[windtrader]

Going down highway, then suddenly started losing power. Temp gauge pegged so immediate pullover. Typical water/stem. Towed home and started once fully cooled. Big white clouds and rough running. Looks like the PHH blew out due to fluid coming from that area.

Since it overheated for a short time but still enough to blow the HG, how often is there more damage beyond the typical HG parts and head rework?

The Temp gauge (Toyota) is not sensitive when it goes to red it is always too late

Theres ‘probably’ no additional damage, but you have plenty work to do anyway.. buy an engine gasket set and use all of it.

Thanks. I'll run a test or two just to confirm that's the core problem. Will order the full kit and have at it. Probably replace anything else easy to get to at same time.
Any general time estimates for competent, non-pro grease monkey to get the head off?
Do most do the repair without pulling the engine?

It can be done without pulling the engine... it should take 15-20 hours to get out and 25-30 hours to get back in and buttoned up. A buddy of mine does these semi regularly here in Austin and they usually quote 40 hours for the whole job. I would definitely do all your checks first to confirm though, this is a big task!
