I had 12:1 compression w/flat tops & 4 valve reliefs.
I used a shaved down 194 head & the engine had 220-230 cranking compression,w/a cam having 236-238 in /exhaust duration @ .050
The pistons came out of the block .002-.004" Thats called a positive deck height,just like the stock LS GM engine have.
Talk about throttle response! Of course 3 DCOE Weber carbs helped also.
I have said it before,,,w/the 3 DCOE's & 12:1 compression,the engine was a torque monster,it was the best combo I ever had normally aspirated,,,& this was w/the 194 cylinder head
