My 87 Subaru Gl Wagon overheated recently. I was offroading and i messed up one of the colant hoses. i think i may have warped a cylinder head cuz there was steam coming out of the exhaust. The steam stopped for some reason but i still think the heads is messed. Does anyone knoe if it is extremely hard to fix the head with the engine still in the car?

I will get in ahead of "search first, ask later" crowd...

 

These heads don't tend to warp or crack (turbo heads being an exception to the cracking thing). The headgaskets can let go after a good overheating... Doesn't help that these HGs are getting old.

 

Passenger side head is not too hard to remove/replace in the car, driver's side is harder. Easier still to pull the engine and do it out in the open where you know that you have cleaned the surfaces and that that little o-ring didn't fall onto the floor...
