Default Engine run time

Hi all

What is the best process to be followed for extending engine run time.

Change of pipe/header??? (1st?)

Does plug and head shim make a difference?

And yes I know leaning the motor helps but there is only so far you can go!

Had an engine at the last state titles that normally has no isses with run time but on that weekend struggled to get 5 minutes. Weather was no different from previous race meets. The only change was changing the gear ratios by going up one tooth on both pinions.

Any suggestions would be appreciated
