Got my turbo set finished but header gaskets were leaking right at start up. I used the gaskets that came in the On3 kit. Can anyone recammend a good gasket for boosted cars?

I have used both. Here is how I see it. RTV works great when you have a flat header flange and flat mounting surface on the head. If they both are perfectly flat you do not need RTV. But perfectly flat header flanges are almost impossible. So you put RTV on and most of it gets pushed out because the mounting surfaces are close to flat. The RTV just fills small voids where the header or head is not perfectly flat. Every thing is great until you put heat cycles into it. Now the header flange starts to warp. It pulls away from the head and the RTV has no way to fill that void. Now you have a situation where exhaust gas can get between the head and the header. This pushes the RTV as well as burns it off. You then end up with a leak.I used copper rtv, works well. Never tried remflex though so I can't say which is better
