Well..., as Johnny Carson would say...correcto mundo there Pontiac breath.....
The most original 17 head of the two (one had been worked on w/ a 45 degree intake seat...) I searchd out the best valve w/ the most margin, and the best seat (all looked VERY good)
83.5 cc's for the 17 head. That puts the comp ratio @ about 8.25:1...yee ha. I have a feeling this 17 head is the same as the 11 heads on my 350 now...
