Any suggestions for gasket replacement or manifold studs.

I’ve modified many bolts and studs to make them work .
It’s all a trial and error work,,,,and all combinations are unique .
Might have to dimple a tube near a stud or nut as well .
I’ve made custom wrenches,,,and even tighten some bolts in sequence to let the pipe hang out a little until I could pull the rest down even .
Headers are great,,,but always high maintenance !
