Review on Fel-Pro 50522 T Valve Cover Gasket Set: Uncompromising Quality for Superior Performance in Engines by Jason Camarillo

Fits easily on my '91 YJ 4.0. I suggest reinserting the bolts by hand from the back first, then moving them forward. Then tighten to specification, starting with the middle bolts and working your way forward in an X pattern. When that's done, fully tighten them again several times until they all reach their torque rating. After a few days, spin them again, after that everything should be fine.
