I think you should have your engine sealed when entering a race.
Once engine is sealed the seal cannot be removed without a tear-down, except for a carb change and the carb should be inspected at this time and re-sealed.
As far as the engine seal goes ,once it is sealed it can be checked at random for any given race and should be told this. If seal has been broken before actual tear-down then it is considered to have been illegal in the first place and should be DQ'd on the spot.
The DQ time will be determined on how many races was run before actual tear-down.
If you know your engine is legal then you should not have a problem with this system.
If you want to make changes before you have been torn down then you still must go through tear=down. Say you went to 4 races before you actually got torn down and you were foung illegal, then the penalty should be 4 races and then come back and torn down before you race and get a diff (certain) color seal showing you have been torn down,.
Also let that seal be good for the rest of the season.

In IHRA ,we have gone to the engine builder's shops and checked engines. After engine was approved it was sealed on the spot and was good for the current year.And has to be torn down again for the next year......Kind of like a chassis cert,but a little diff.
