I gave away a set of -8sp Brodix heads last fall, but they needed repair in one chamber...

Brodix and AFR make spread port sbc heads, with the center exhaust ports slightly spread to make room for a coolant passage between them. Completely different exhaust bolt pattern, 2 bolts angled for the end ports, 3 bolts for the center two ports. The bolt pattern makes it easy to put big tubes on, but really limits your off-the-shelf header choices. I have a set of spread ports on my sbc powered car...

That's a Stahl flange head, not a spread port.

Sorry, but seeing how both AFR and Brodix, who produce these heads label them as Spread Port, so I'm going with their description of their own product. BTW you're not helping.

Back on thread, is anybody able to assist?

Note the distance between the center exhaust ports in the above pic, then please explain to us why that's not a spread port sbc head?
