Trickflow Powerport 190 heads and TTI Headers

I called Bob Mazzolini to order 1 7/8 TTI race headers for the 408 we are building. He called TTI to place the order for me and he said that they are concerned from looking at pictures that the header may leak at the bottom on those heads. He said they have not seen one yet in person. I explained that they are suppose to be standard port but I guess something looks different to TTI.

I am wondering if anyone that has done a build yet has installed TTI or other headers and have had any leaking problems? Bob suggested I get headers from Powerport and send them to TTI. I am going to check summit now but I wasn't even sure if they did there own gasket.

Thanks

Kevin.


The exhaust sealing surface on the TF head is HUGE. I can't figure out what the issue is. A 1 7/8 header seals on an OE head, so why won't it seal on the TF head?
