Although primarily designed for the Chevrolet V8 Engine, these lifters will work equaly well in a Rover V8 engine - top quality !
The physical size of these lifters will allow fitting to the Rover engine however the ball rad. of the lifter cup requires a non standard pushrods.
Hollow tube chrome moly or adjustable pushrods will need to be used.
To aid assembly and to prevent premature follower and cam lobe scuff consider using Cam and Engine Assembly lube.
