@isptbart I should probably mention this as I don’t want to cause you more troubles... If you decide to use the RemFlex gaskets, you will need to do them all. They are much too thick to replace one or two of the OEM ones.
Might also suggest getting the set for your engine versus buying a sheet and cutting them out yourself to save money. I tried that, they do not cut worth a d***, so I ended up buying the proper stamped set from their website and basically paying twice. 😡
It’s quite a tough call to make on chancing replacing the two leaking gaskets with OEM, hoping the manifold isn’t warped and the bolts will come out fine or get yourself into the situation I got myself into.
This is how warped my manifold was…😭
