Re: "lifter tick? Suuuure"
Have you re-torqued the exhaust manifold bolts since you had the gaskets replaced?
If you suspect a leak whether it is in the exhaust, intake or vacuum system you can always get a shop to use the air conditioning smoke dye test. It smokes like crazy and if you don't happen to see or catch all the leaks it leaves a florescent dye that can be seen under a light. If you have a leak it will find it.
