hey how are you

did you check the manifold itself for warp page ?

take it out and lay it on flat table and see or send it to machine shop for them to check ?

you should be sealing , if you replaced the bolts & gasket and torqued them

you might have to replace teh exhaust manifold itself

Please let me know

Thank You
