Headers for 365/390 Cad?

Does anyone know a source for headers for a (331 - ports too small) 365, 390 Caddy?

I've seen the flanges and lakes style but need some fairly tight down style with center outlets.

I'd consider some stockers (driver side only for the center outlet) if you've got some.

Thanks, Don

 

Just got a pair from Sanderson for my 331 Cad., very pleased! I'll need to open the ports on the 331 heads but would ***ume they'd be a perfect fit for the 365/390 motors.
