The MPH always went up also. Certain brands of heads have seen an improvement of 4 to 5 tenths by correcting the OEM C.C.'s with the work.. The bracket racers in Maryland near Budds Creek used to think I could walk on water...LOL. Some of their stuff was pretty much junk to start with though. Its been about 12 years since I did any of that stuff. I got tired of my dinner tasting like cast iron, retired and moved to Fla. .
I also know it for a fact several guys are still doing it. I used to touch up (freshen up) the valve jobs on their heads and have seen what was done. I will NOT mention names because I do not want to start a war. Its not fun anymore at all !

Thank you. I never knew it would have been as much as 4 to 5 tenths. I need to get out more often
