AFR 195 heads exhaust port shape
Can someone with AFR 195 SBC heads tell me if the exhaust ports are D shaped.
Nothing on search and AFR has not replied.
My Headman's are D shaped.
Thanks.

Info for anyone doing a future search on this subject.
Took D- shaped gasket for my Hedman's to local speed shop and compared to exhaust ports on AFR 195 (AFR 1034) heads with rectangular exhaust ports.
The D openings are larger than the AFR rectangular exhaust port openings.
So the exhaust gases will flow freely. Yee Ha!

Interesting. My AFR 195s were D shaped when I received them. However, after I had them ported they were square. They must have stopped using the D shaped port.

Quiz for the day: "What is the purpose for the D-port shape"?
The real question is "What shape of header tube do want for a D-port head"?
For street? For race only?
Why did GM use the D-port on the L98 head?
