fitment question

[Facey]

Hey guys
i am unsure of the answer, so i figure this is the best place to find out.

i have 1 3/4" S.S. B&B headers (w/heat) for carrera heads.

this means they are well suited for:

carrera heads for sure.
964 heads????
sc heads????

what discplacement are these well suited for?
3.2L-3.8L?
3.4L+
??
- not 993 heads, as i know the flanges would have to be flipped.

i am asking because they are for sale and i would like to be able to answer, with confidence, what they will fit.

thanks
Nick

anyone wanna clarify?

How about a picture.
the port size, as I understand it, is the biggest you want to put on a stock 3.2. I think it will be too big for a 3.0 unless the 3.0 has been built to run higher rev's than stock.
What does B&B recommend them for?? That would be a good place to start.

I've used them on both 3.6 and 3.8. They work well in both of those applications, they do work better w/ lumpier cams than w/ stock

on 993 heads the exhaust studs need to be relocated.

probably a tad big for a street 3.2 w/ stock cams

thanks guys.

B&B sold them to me for a built up 3.5L using carrera based heads.

that isn't the most common engine, so i though it would be nice to able to say exactly what they will fit.

and what they will work wonders on.

on a 3.2L if they add a S.W. chip along with the headers there should be a good amount of gain, this is for a track car...
