There wasn't a pair of 5.8 valves available for photography during our SVT visit, so this pair of 5.4 valves is standing in for them. In the case of the intake valve on the left, it doesn't matter as the 5.4 valve is carried over without changes to the 5.8. The exhaust valve at right is at least a visual twin to the 5.8 valve from this angle, but the 5.8 exhaust valve is made from stronger, more heat-resistant metal, including a super-hard inlay of Stellite around the seating face. The 5.8 exhaust valve head does not have a bowl like the intake as that area has been filled in for strength.
