Ok i see what u are saying so it could be slightly misaligned. Well I'm still letting the ultra copper cure for the night and I will see how it does in the morning. If no good then I guess your suggestion will be next on my list. Thanks for all your help and I will keep everyone informed

Here is another pic. This was my intake In the circle there you can see the fresh shiny aluminum on the head where that clocking flange was bumping up against it and preventing it from sitting flush with the head. I filed some metal off the clocking flange so it wouldn’t hit the head anymore and sit flat. Drove me crazy trying to find that leak until someone told me about how that happens. I tried all sorts of gaskets. The flange was just a little to big for the space provided. Even though it bolted down it still left a little gap cause it was crooked. So you can hopefully kinda see what I’m talking about. I hope that your prob because it’s an easy fix. Good luck! Post results!

If this is a leak at the exhaust port on the cylinder head, it may be helpful to place the exnaust pipe in place along with a copper 'ring' gasket, and tighten loosely. Then, support the exhaust pipe & muffler by hand, taking up all the 'slack' so the pipe fits snugly against the copper gasket, and is 'flat' against the underside of the head, on the exhaust port. Leave the muffler end 'free' to float to wherever it wants, but support it. Once you get the pipe pushed flat against the gasket & head, tighten the long acorn nuts evenly, and then do a final tighten to torque. The whole time the exhaust pipe & muffler are supported, pointing to wherever they want to go. The pipe should be sealed and quiet when tight. It should NOT rick back and forth at all. The fitting on the end of the exhaust pipe should be flat & cleaned of deposits & dirt, etc. Before fitting, check for flat by placing the fitting on as flat a surface as you can find. If it does not contact evenly, you can 'file' it against concrete sidewalk or concrete 'block' to get a flat surface. It may need to be 'adkusted' if either of the ears has been bent. If bent towards the inlet(head side) the ear my not pull the fitting tight against the gasket or head surface. Then it's hammer time to straighten as much as possible. Once fitted, and tight, you can check for leakage, or maneuver the muffler to where you can install the fasteners to the brackets. The pipe can be bent to relieve the tension if it wants to be 'somewhere else'. tom
