When I ran the small chamber 194 head & 12.1 compression,positive deck,,running 91 octane & 3 48 MM Webers, it was very streetable & was my daily driver w/over 220-230 cranking compression.
This was the best combination I ever ran on the street & fastest normally aspirated combo w/the 194 cyl head.
Never raced @ the track,, but,raced my friends cars to compare,,it was an easy low 13-mid 13's car in the 1/4.
