most likly its a leak,as I have chased a "lifter tick" with all my headers my brand new headmans leak where the 4 tubes meet at the collector right from the get go I used the copper rtv on the header gaskets,and let cure over night,that has fixed most of them the new headers have a ball/cone set up down below so no gasket there now,that was the one that would go every time it rained for me and nothing is worse than brand new high dollor headers and gaskets that leak take a 2-3 foot piece of water hose and use it to listen around the tubes and header flange also pull your vc and use the wood handle of it to push against the rockers as it runs,this will let you know which one is ticking,it will quit ticking with you pushig against it do you hear it in the car only? can you hear it under the hood while running? most time I can only hear it in the car,never out side the car and under the hood good luck

This is easy. To find an exhaust leak, take a piece of hose, say, 3/8 fuel hose, and hold near your ear CAREFULLY. Search around and if it's an exhaust leak it will "blow in your ear"!!!!

The chunk of hose trick does work well.
If you want stereo use one in each ear!

Never tried this but how about removing the rocker shafts to close all the exhaust valve or seal the top of the carb.
Then plumb air or vacuum from the shop vac in the exhaust pipe.

Great advise, I used a peice of rubber 3/8" fuel line and found the leak right away.
Hate to say it but it was the TTI headers that leaked from day one. I didn't think it would be them as they were new but there was a crack right where they were welded to the flange at the number 5 exhaust. I took them off for the third time and could see day light thru the flange. TTI ground the inside pipe before coating and it was real thin there with no weld penatration. I ground it clean on inside pipe and tig welded it back togeather and now the car is quiet like it show be. The motor even runs better. This has kept my car in the garage for like two years now. It was so depressing that I didn't even want to drive it like that, it sounded like crap. I'm thinking about emailing TTI to let them know of my troubles, I bought the headers from Indy Cly Head in Indy one day when I was driving thru there in 05. I hate to complain to anyone after that long of time. I wanted to thank everyone for the help and the mechanics stethoscope really works.
