OBX long tube gaskets

Tedmeister · 11-06-2020, 03:54 PM

I'm in the process of installing OBX long tube headers. Should I use the
metal factory gasket, the ones that came with the new headers or RTV.
I'm mainly talking about where they attach to the block.

I reused the stock oem gaskets when I did my FI LTH's. That's been 7 - 8 yrs ago.

I'd go with OEM gaskets unless the headers came with 3rd-party gaskets and they match the ports well. I try to avoid RTV on the exhaust. YMMV

Good enough, I'll use the factory ones. Not too excited about the OBX headers.
I didn't realize they were made in China, so the build quality isn't very good. I'm
sure the gaskets are not good quality either.
