U-20 Header Options

[TAD240@aol.com]

I am searching for a high quality / high flow U-20 header.  Any opinions out 
there??  I really want a header that has exhaust port openings at least as 
large as the exhaust ports on a stock U-20 head - maybe a little larger.  I 
have 
a header but the ports are actually smaller than the exhaust ports on a 
"stock" head.  Can't stand the thought of an obstruction at the outlet of the 
exhaust port into the header.
