89S 350 TBI Head Gasket Replacement Project

you want a 195 t stat in that

I was told by chevytech on 67-72 to not run anything under 195 in a computer controlled vehicle because of the closed loop and crap. I think mines lower and it only goes into that mode when it's like 70 or hotter outside and after a few miles on the highway, around town it never gets warm enough.

I just got a call about the heads, the guy had them on the shelf, they match. He's assembling them today and they should be in my hands by the end of the day tomorrow.

I got a 195 to put in mine when I switch hoses and put on the chrome water neck.

I got to pull off the driver's side head and exhaust manifold that I already installed. Looks like I will be breaking out the extra pair of manifold spreaders after all. Should go nice and smooth though since I had it apart already. The pass side is prepped and ready to go. I'll start attcking this **** first thing Saturday morning.

I do have a question, are heads able to be put on either side, are they the same? Or is there a right and a left?

 

[Swims350]

they are usually the same, as far as I can remember, just make sure it has bolt holes in the front where you need them. Maybe on some of these newer ones with the water port it might make a difference not sure, so just compare them.

You got one head on already? a bad head? you have to get moe gaskets now?

Yeah, he got me a set of Permatourque gaskets. And I need to pick up new exhaust manifold gasket for that side too. The head I put on already looked fine to me. Didn;t see any cracks and the flatness checked out to within specs.

as swims said just make sure the bolt holes are the same, but pretty sure they can interchange, i might get bashed for this but i would ruuse the exhaust gasket you put in since it did not have any heat on it

 

[Swims350]

if they are the alum type exhaust gaskets, yes I would 2nd reusing them. if they are paper you could too, but I hate the paper ones period.

I was wondering the same thing about the ex gaskets too.

I know that there is a spot in both heads for the coolant sensor, just one is blocked with a plug that doesn't use it, and it is on the same spot on both heads, towards the left side when you are facing the exhaust ports. That's what got me wondering about if the heads can be used on either side. This is all new to me as far as hands on doing it.
