So let me understand
If you dont do shaft oiling you would need to do pushrod oiling - correct?
Do aftermarket heads do shaft oiling?
Thanks in advance
They are either setup for LA oiling or MAGNUM style push rod oiling.
You can do both if the heads are LA style. If you arent sure which you want to use.. just get an LA oiling style head and you can use on both with the addition of oil through lifters and push rods.
