Got my cams through post ( thanks Steve ) but I just want to know the lift/duration of the inlet cam so I know if i need valve clearancing as RB said they can't tell what cam it is but it isn't standard

Auto part Metal
Calipers Measuring instrument Technology Tire Electronic device
Tire Automotive tire Auto part Calipers Automotive wheel system

It also says N401-001 on the back of the cam

Duration does not effect clearance. They are 9.1mm lift.

No Daz . need to remove cambelt and swap cams over and check clearances with feeler gauge before put back together . Its more time consuming than it sounds but if all clearances are fine it can be done in a day

easiest way to check is get a micrometer not a vernier and remove the 2 camshaft covers and measure lobe and compare to the new one . dont need to measre lift , just smaller diameter like you have in the first pic but where the valve wont be in lift

You will need to check and probably re-shim the head with every cam swap.
