Picked up a set of Manley +1mm valves, forgetting the gen 2 heads saw an increase in valve size. Are there any true +1mm valves out there for gen 2 heads?
and if running a gen 1 +1mm which increases intake by I believe .7 I take and .3 exhaust size on gen 2’s, would anyone even bother increasing valve seat size?
