I see where youre coming from Jman, but id put them in as not many people really want to have to pull a head or engine out more than required!
sump has to come out to be modded, so id pull the head, fit restrictors, get a decent sump with gates, fittings for your breathers.. dont do the head mod...i can name quite a few big names that do not fit it.
get a decent breathing setup with decent catch can.. done...
if you really want a safe engine, upgrade the oil pump.
but id just wait till it pops, then rebuild time!!
