Default Oil leaks and no power

Hi the screws dont need to be that tight, thats why they have those heads ,the gaskets have gone hard from from age and need replaceing, If the engine as a exhaust leak it wont make boost also the cat could be blocked fix the leak then run it with the front pipe off the rest of the system and see if it goes better Phil

Indeed, and over tightening can ruin a good seal. The torque spec is 23 INCH lbs... NOT ft lbs. Hand tight is pretty much it; Hence the philips screws versus bolts.

Well I tightened them down as tight as I could by hand. I got up in the engine bay to make it easier. Do you think I may have over tightened the valve covers

Well, it's hard to crush new seals by overtighteing by hand with a screwdriver... How old are the seals? They may have cracked or they may be compressed from age (they may still be very flexible in this case, that doesn't mean they're still good).
