exhaust manifold bolts are snapping

[matt1967]

all of the bolts are out now, all came out clean, no stripped threads or drilling. now, should I get New original style bolts for the manifold?. www.dearbornclassics.com sells original style " Ramp Lock " manifold bolts for the 170-200's for $17.95

I'd put studs in instead. Those original lockwashers were effective, though.
