Developed to be the optimum sized inlet valve size and shape to fit in small-bore A-series cylinder heads for all bore sizes. Seat to collet groove is correct length for all small-bore heads, so not massively thick rocker pedestal shims needed. Consequently rocker adjuster screws are not hanging a long way out of the rocker. Made by Europes premier specialist valve manufacture for CST in EN214N steel.
Only suitable for bronze valve guides.
