Well I would think the lobs on the cams line up different to the exhaust & intake valves. You look at the location of the valve, the ones over the exhaust ports, where the exhaust manifold is bolted to the head, of coarse are exhaust valves.


The exhaust valve is the closest to the exhaust manifold.
