stock it is. I pulled off my TB yesterday cause it was sticking when i moved my car out of the garage to reposition it, and noticed the inside of the IM isn't that dirty/oily anyways so i'm not pulling the IM off.

Do not use plastic gaskets!!! This is a copy of a earlier post I had made regarding the same issue. Plastic gaskets were obviously designed by some one with no engineering back ground.
What happens is that the pos plastic gasket can support some torque at lower temp's but as you increase temperature the creep rate of plastics skyrocket. So even if you do not overheat your motor, the plastic gasket will still creep and the bolts will appear loose, when in fact they have not moved at all, rather the shitty gasket has shrunk from material creep under torque.
And it gets worse, if you do overheat your motor, the plastic becomes liquid and begins to squeeze out of the gap between your head and IM, at this point water from your cooling system floods the closest cylinder and you destroy yout motor! Wow this plastic pos gasket is sounding better and better, huh. Especially for forced induction guys whose motors run hotter anyway!
That being said , I would never use this pos gasket, not even on my lawnmower. Just go back to the stock IM gasket, and call it a day. the 1 or 2 hp that this gasket makes is not worth the headaches.
For those of you who dont know what creep is here is the wiki link.

Notice in the article that plastics can creep at room temerature, just imagine what happens at 300 degrees!!

your a jackass...............don't you think they used a material that will withstand the temps? the shitty ebay knockoffs are the ones you have to worry about......but to each his own......

Also the link you have in your previous post is to a completely different gasket than the one we are talking about jackass.

I have absolutely no idea what material the Hondata gasket is made out of, but there are high temp plastics that are resistant to creep to near 600 degrees farenheit. So its not a given that well made ones are going to melt and creep. A simple google search will find many that are good well past 400 degrees and I found one good up to 570.

and which one is that?
They claim 572 degrees. Google "high temperature plastics" and you'll find a couple dozen products good beyond 400 degrees pretty quickly.
My setup runs fairly cool but I don't know that I would use a plastic gasket in a high hp turbo application.
