Ok guys this is for all of you with a 24v that have replaced you OEM headgasket with a 20 thousandths over marine gasket.

How do you like it?
Does it smoke upon startup?
Any trouble starting?
Loss/gain of noticeable power?

Also please post if you had the head milled and if so how much. Also please post if you have an ETC or an ETH. I have 3 trucks that we are O-ringing and I am considering using this gasket. All of the trucks are between 500-600 HP single charger with boost levels below 60 psi.

Thanks for your input.

Doug
