Will thess hp manifolds fit my car?

[383Satellite]

WIll hp exhasut manifolds with ttese casting numbers fit my 71 Satellite with a 383? The casting numbers are 3751071 for the passenger side and 2843992 for the driver side. I am pretty sure that the passenger is the same number used for the 71-72 cars, but the driver side is from a 68-69 b body I think, will that fit? Is this a good set of hp manifolds? Thanks Steve

I'm not a big block guy, nor can I answer your question buy just reading the casting numbers.
By chance, can you post a picture. You see, even with the casting numbers, many may not know what they look like. Even though there on there car right now. (LOL) But it's true.
Some one may say, Hey, i have those on my car right now. And then they could take a peak to be sure the numbers are correct.
Numbers can be a tricky thing. Some times, different casting numbers can be on the same exact part.

I think all B-body exh manifolds will fit. The main difference from casting to casting is the position of the head pipe flange. If your having the exhaust made, no problem, but factory pipes may not bolt up.
