who told you that ? anti foam is NOT keeping your engine clean its the detergents/dispersants in the oil.detergents and dispersants are what keep the motor clean.dispersants suspends the by-product of combustion.amsoil is a prime example of a high detergent/dispersant synthetic oil.detergents help to reduce the formation of deposits.

anti-foam.foaming causes air bubbles.air compress's much easier then oil thus lol not lubricating as it should

 

THANKS!!! (hence the whole CLEAN thing)

I can assure you that I did not swap the heads. I would not swap stock heads into my truck, they would be performance heads if i was spending any money. And if I paid the 750 (heads I want), I would surely put them in my sig.

The transparent silicone gaskets are still on the heads in that pic.
