New Small Block Stroker Engine Noise

It was definitely leaking on the front because I see the carbon on the header where it was coming out. I believe what was happening was it leaked badly when cold and when the header heated and expanded it would hit the gasket enough to seal some what because the car quieted up a lot when hot.

A friend of mine at work used to make custom headers at his previous job. He did nothing but that for 10 years and his work is world class second to none. He is an unbelievable fabricator. I took the gaskets in to show him and he said "you must have had a big leak". Anyway, he has offered to modify the headers to get them to stop leaking but it will mess up the finish in those areas. He needs to see the headers off the car before he figures out what can be done. I'll be taking them off tonight.
