The other stud snapped off even after 3 days of PB blasting. PaulPud removed the heads and had a machinist drill them out. Took the guy 3 hours with tons of cursing. Replaced all the gaskets with cometic kit and cleaned out the combustion and intake chambers. Applied tons of loctite to the drummer ss front mounting bracket. Back in business.

Anyone have any advice on how to prevent the front header studs/bolts from getting so corroded again?
