Exhaust manifold ID

[bull]

In reference to my other thread, where some of you were asking about my exhaust manifolds, I now have pics. These are bolted to what's supposed to be a low hp 383 and I'm trying to determine if these will be good manifolds for a mild performance rebuld or detrimental.

Looks like you have a HP on the drivers side and the standard manifold on the passenger side. We bought an untouched '70 383 2 bbl automatic Charger with the same setup so I am not sure why that HP shows up like that sometimes.

Here are a couple shots of mine. The passenger side HP manifold should look like this but, it has had the valve for warming up the engine removed and brazed shut at some point in time.

 Yep, missed match pair. Right one is the none HP log type.

What are the casting numbers on them?

Wonderful. That's exactly what I was afraid of when I got a good look at them. I'll have to post the casting numbers later tonight.
