F-Body Round Port Headers?
 

I thought this would be simple enough. Aparrently not. Back in the days of "D" port heads, I used Hedman headers on my 1967 Firebird. Perfect fit! The new motor has round port heads. What are you guys using these days? (67-68 bird w/round ports) I cant seem to find any headers with large primary tubes for a high HP application. I looked at Hooker & Headman. Am I missing something? :(

Jere Stahl..... although, what is shown in the picture utilizes a sort of square/D port flange..... Jere will do what you ask if you are looking for round.
