If the op isn't I may be, but not until he's had a chance to decide.If you are interested in some shorties I have a unused set of JBA’s I’m not going to use. The EGR pipe and air connections are already cut and tig welded up.

I 100% plan on better heads and extrude honing the factory efi manifold.Perhaps a moderator will move this thread to the "Exhaust" sub-forum.

Big-tube headers are almost certainly a mistake. You'll be unable to rev high enough to need that capacity; the L29 heads are dogs above 5K rpm.
The smaller tubes are better for this application. Higher velocity, better scavenging, more performance, less cost, easier fitment. There's essentially no downside.
How about a set of Sanderson headers ? They came out of a 1965 Biscayne 502.How much?
