Forgive me my Mopar brothers. I have sinned

that 5.0 I did I bought a new valve and hand lapped it in.. worked, but the seat wasn't jacked up. it was kind of strange kind of lucky at the same time...I test them with light oil like naphtha I level the head up pour it in see how long it takes to seep. I know this sounds like "Uncle Tony Baloney" but it works...
