Default Ceramic Coat Pistons Or Not??

I've seen a couple of threads here and there discussing this . . . would you do it or not if building a new FI engine? State your reasons for either argument, I'd like to do this right while I have the chance!

You can. Coating the piston keeps more heat on the top of the piston.

If I knew that Diamond sold coated pistons, I would have bought them instead of the standard uncoated 3.905's I got from them
I dont have a FI motor, nor do I plan on ever having one, but I definitely prefer coated parts. Oh well, too late now

We use the same coating facility that Diamond does, if you want them coated just send them to me.

Give me a call at the shop and I'll get you prices.

YES!! I installed Diamond coated pistons in my forged assembly. I had an unfortunate incident at the track one day on nitrous. I clipped #1 and melted #3 plugs. It actually detonated so bad that the combustion chamber plug shrouds melted off. When I pulled the head to have it repaired, I did not have ONE mark on either of those pistons. It could have been just plain luck but either way it made me a believer in coating.
