Headers

[rdobbs]

Helping my son build another 383 sbc. He ordered several parts
about 8 months ago. Among them were a set of headers and a
set of profiler heads;however he cancelled the profiler heads
order after 8 or so weeks since they were not available and got
the run around.
He has since ordered a set of Brodix heads which have rectangler
exhaust ports. The headers he previously ordered for the Profiler
heads are oval port.
Must he get headers to match the Brodix heads or can he use
the oval on rectangler?
Car will be a daily driver.

For a daily driver I'd be sure that the gaskets seal and run what you've got. The mis-match may create a bit of turbulence, which is actually a help in scavenging the cylinders. Matching ports doesn't really add much value, especially at low to mid-range rpms and at cruise.

If you can make it work without leaks, go for it.
