I don't get a bingo? Shucks.

 

Yeah, you get one too, I just don't know how to do two quotes on one post! I'm still working with rocks and sticks here!

 

Glad to hear it was a simple fix!

 

Well that's good news Vall.

 

Man it sure was good news to me! Of course you might guess the first thing that came to my mind was, "maybe that's why those heads were so cheap!"
I woke up 4-5 times last night thinking about it, and trying to figure out what I might have done wrong, but just couldn't come up with an answer. I'll sleep like a baby tonight!

 

Glad you got it, and glad to help. What you're experiencing with your head temperature can be considered normal. Aluminum dissipates heat faster than iron, and it also transfers heat faster. So what you're reading is combustion heat, and quite possibly exhaust heat from the headers getting absorbed into the heads. Your gauge is reading head heat, not engine heat. What you could do is move the gauge to the intake manifold, as that coolant is on it's way out of the engine and heading to the radiator. Or be trick and run two gauges; one in the intake manifold to read engine temp, and the other to watch the head temps.

 

That's an excellent idea, and I wish I had thought of it, but I don't have a threaded port on the intake. Had I thought of it before installing the intake I could have easily got the drill out and tapped for a gauge pickup. If I have it off again I will, and I will surely go the two gauge route to see how they differ.
Now I'm wondering if I could pull my swivel Tstat housing off and D&T for a pipe thread there? That would tell me temp when the stat opens too!

 

Well....I was going to suggest using a t-stat housing with a threaded fitting, but you just took the fun out of it.
I don't know that your nifty swivel housing has enough meat to drill and tap a deep enough hole though, to catch a decent amount of threads.

 

Could be right. I thought if it wasn't thick enough I'd use a two piece O ring fitting with a threaded receptacle. Looked at threaded housings yesterday, and they're pretty proud of them!

 

I have a stock one out in the garage. Its aluminum not pretty but it works. Look in the bone yard for anything with TBI.
