Best sealant to use between header and crossover pipe

[Jay J]

I was wondering what works the best (and what doesn't) when sealing the connection between the header outlets and the crossover pipe? TIA...

Anyone? This is for the stock headers, not the ones that take a gasket (v-band).

I don't use any and have no leaks

Make sure where the crossover meets the headers that they are round and not oval.

Thanks for the replies. I saw some old posts about using the copper RTV on these, which seemed to me like it would cook off
as soon as the engine came up to temp. Should be a piece of cake because it is sitting on the stand and should be easy to get it aligned just right...

Crossover has to be off if you are running stock trans lines.

Took care of that years ago... But that info may help someone else.
