Help me sort out a 10 second build

I like simplicity. I’m not a test n tuner, change parts and test again so I want to do it right and only once.
I’m sure you didn’t arrive at your combo day one, wouldn’t be the accumulation of your years racing and when you build a new engine any changes would be based off your experiences to allow you to get it right in first go?

I threw my 2 cents in the OP can do whatever he wants.
