I'm sure you can fit 1.1mm oversize valves on the xe head but 2mm is the max & the seats need redone

I have heard about fitting a xe cam to the let head cant remember if it was the inlet or exhaust I'm assuming its the exhaust??

Regarding the ZLET oil pump how is the pick up modified & does the let engine come with a baffled sump or does this come
from another engine??

Thanks Buddy
XE Inlet cam is the one you need mated to a Vernier pulley for adjustment.
