Any advantage/disadvantage to using stainless bolts in aluminum cylinder heads?
I've got a 2006 GMC with 6.0 gas. Since the OEM exhaust manifold bolts are known for breaking I was looking at, say a ARP, replacement but I live in the salt belt so stainless came up on the radar.
Not sure if the OEM bolts break due to poor metallurgy, shearing from expansion-contraction or embrittlement caused by thermal cycling.
