My car has a coolant smell when driving and its just a strong smell that goes away with in 10-15 seconds. The radiator cap ,waterpump and the heater core are all new?

When I turn on the ac the smell disappears.

If you replaced the heater core because it puked on your carpet, that's probably where it's coming from.

JFP installed cartek stage 2 heads and cam with a ported ls6 intake .My car is a 98 how do they run the coolant cross over pipes at the back of the motor when they install an ls6 intake ?

Don't know about the coolant crossover.

How long ago was the work performed on the cooling system? If you spill coolant and don't wash it off good you may have a smell that lasts for about a week. Anything more than that and it IS leaking from somewhere. Were the old spring clips re-used on the hoses? They can lose their tension when they are removed and should be replaced.

Well if the smell as anything to do with on off a/c or anything with the blower motor thats only a heater core.

FWIW my car will randomly stink like coolant in all kinds of different situations for almost 3 years now and its never had a single issue with any coolant or cooling related problems. I always thought it was just another perk of owning an f body
