Headers

[krops cars]

I built a 440 six pack.I have headers on it. After running awhile I noticed a tic on the passengers . I thought at first it was a lifter. Pulled valve cover checked out ok. Found header loose. Tighten up. Still tick. Ordered a pair of copper gaskets. Noise still there, but different. Had a friend come over just to see if he hears what I do. So I told him I will take my welding gloves with the car running and put my hands over the tail pipes. When I did this the tick went away I thought it would get louder. What do you think? And actually after I did this a few times. Then tick got quieter.

Could there be a leak at the header pipe to flange? Maybe in a spot underneath? I've tested this with water, pouring it on the tubes one at a time. The leak will make a burble type sound like when you "motorboat" a woman.

I torqued mine to spec from dougs header instruction and used stage 8 locking bolts, never had an issue going on 3 years
