Years back I won class at the gators and went through tear down. One of my intake valves measured .001 under the low limit. The valve was badly tuliped. I was tossed for the event and had to show up at the next event with the head off and have the valve size checked before I could race. I was also placed on 6 mos. tech probation. That infraction was considered minor. FYI I put new valves in the heads for the next race and the car picked up a tenth.


Did you know that the factory tolerance on a micrometer, Dial indicator, or dial caliper is plus or minus .001. I know this because I used to calibrate precision tools for the Dept. of the Navy. They should be checked with "GAGE BLOCKS" a least once a year. Tools being treated to rough treatment as in running all over the U.S. should be certified at least several times a year. Do you really think most tools being used by the NHRA tech. dept. have been certified?
