Ticking noise need new lifters? 360 v8

I have some gaskets so I'll change them and see. Just surprised an exhaust leak can give such a crisp tic! Thanks for the replies :)

You can use a piece of hose about 3 foot in length as a stethoscope. Hold one end to your ear and use the other end to move around the header flange and pinpoint the leak if that's what it is.

It sure sounds like it.
