Header seating..

360 engine / tti headers..

We cannot get a really god seal around exhaust port #1. It is leaking below the port.

It almost looks like the header is hitting an casing bump. Too the header off but still do not have the room to get a grinder (or even a dremil ) in between.

Was think the only alternative would be to slip a bit more gasket material in between the #1...not sure what effect that would have on the next port down...

We have re-tightened after heat / cold cycles....

We are stumped.

ideas ?
