They still had overhead camshafts, water-cooled crankshaft bearings, superchargers, etc. To do a valve job, you started by removing the rear axle. Reliability at a cost! Jordan

Thinking out lous: Might head bolts be tighter on iron engines than aluminium engines? The old wisdom might rely solely on the compression of the gasket by the head bolts for sealing, whereas nowadays with alloy heads the bolts aren't as tight and a sealant is necessary?
