My car has a trick flow top end around 4K miles old. Passenger side intake gasket is leaking oil down back of motor. Going to tear down and replace what other gaskets should I do while at it? My trick flow valve covers always loosen up and leak. Looking at getting ARP stud kit. Which valve covers gaskets should I get?

I also have a EGR delete kit and my new intake gasket have EGR blocker. Should I install them and delete egr? I'm switched to mass air conversion would this cause an issue?

Thanks
