i have an oldsmobile 403 and im putting 350 heads on it to rasie the compression to 9.5:1. I will be using headers and alumium intake with a factory 800 cfm carb. the intake valves on the 350 heads are 1.875 inches. I've read that smaller valves increase your low end torque. but in this case are they too small causing lost of power. im going be using this car as a daily driver. and would like to use it to blow the little rice rockets of the line.


Any answers are greatly apreciated.
