What is this and what is it for

[Ahmad Darwish]

That is a high compression head, you mount that at the top of the motor, and should boost your torque. Depending on the compression ratio, you might need to run a higher octane fuel.

I have no idea what this is or what it is for

I got the same head with my GT5 PRO RACING engine kit from Kings motors.

Or move to someplace on the equator, since time and speed are relative, going 25mph there will make you appear to be going 26mph to somebody standing on the north pole! And you'll weigh less too!

Yes, if there's already a head on the engine that means they sent you a spare, you can use it right away or use the original first and see how you like it

I purchased a GT6 , it came with both heads, they recommend using the stock head until the engine is broke in, then change to the cnc head, I'm sure someone can tell us how many miles are recommended for this period.

I like to call an engine 'broke in' after about 100 miles. That way it gives everything a good amount of time to take it easy
