Been helping my son put together a 383. He ordered most all parts
8 months ago. He ordered a set of Profiler heads and waited 8 weeks
and they kept giving him the run around so he cancelled order and
bought a set of Brodix.
The headers he ordered were oval port to fit the Profilers and the
Brodix takes the rectangler ports.

This car will be street driven 99 percent of time. Question is can
the oval port headers be used on the rectangler Brodix heads, and
if so will this hurt performance.
He has over $400 invested in oval port headers and to late to return.

Thanks
