Bad heater core

Well I found my first real problem with my toy. When I bought the car I noticed the heater core was bypassed , I asked him about it and he gave me a story about some kinda performance gain. I didn't beleive him about a gain but I had read of other people doing this to. I even asked him if the
Core was bad and he said no. I would have bought the car anyways but would have fixed the problem before it started getting cold.

i dont know any kind of gain you would get from that considering your heater can actually help keep your water cooler.

Replacing it is a bìtch, it requires removing the entire dash. Here is the RnR from the Shop manual...

In the process of replacing mine as I type this. Not something I want to do, but I refuse to pay $500+ to have it done.
You are right tho. Its a real pain in the bottom.

That's what mine looks like too.
Is there anything else in that area that I can change out since its all ripped apart?

Going to do that too then. Waiting on another person to help roll the dash back.
In the meantime, is there any visual way just by looking at the heads and intake whether its been swapped with pi?

Don't know for sure, but I heard you can put a pi manifold on non pi if you drill a coolant hole somewhere.

Ye I know that lol. When I bought my car the Guy replaced something in front of motor. He said it was plastic and was bound to break. My mechanic said the intake looks like it was replaced so I'm hoping it has pi intake. Save me from doing it. Even tho ill have to pull it to replace cams.
