I have a 1998 Ford E 150 making a loud ticking sound?

I believe the head gasket or head gaskets are blown this problem has been going on for about a year when it first happened I put a couple of bottles of Blue Devil in it and it seemed to stop the antifreeze from going in the oil at this time there was no ticking sound but recently the same thing happened again antifreeze in the oil but this time there's a loud ticking sound if I change the oil and head gaskets and put a bottle of Lucas in it as I always do when I change my oil will this stop the ticking sound

It sounds like the fetzer valve has thrown a flange

Blue Devil, I think that's sodium silicate (water glass) It may have plugged a oil passage to the lifters. So I doubt the Lucas will clear it. But you never know.
