I am restoring a 67.5 2000L and want it all original. The one I have needs a lot more work than I thought and trying to see if there is another option.

There are no smog ports drilled into the non-smog head on the intake/exhaust side. They came on the early U20 engines (67 2000's) making them one of those unique half year parts. Of course useable on your 68 or any U20, but sought after by 67 owners going for the original look per the WTB request.

Its one of the parts Ive wondered about on mine. Mine is an early 68, which I believe was built in 10/67 based on the VIN. Block is the original one too, though this motor has been rebuilt at some point between 68-86 when it got parked. Also has the early Solex carbs, so who knows what the history was on it. Ive tried unsuccessfully to get in touch with the person who I believe built this car this way.

I might be mistaking but seemed to recall that all Canadian U20 engines are non smog
I do have one and pretty sure it’s from a 69

I don't think that it was all Canadian cars, but certainly most

They are so lucky up North then...no need to deal with trying to block off those ports.

No that doesn't sound right to me. The cars with non smog heads stopped being delivered to North America in early '68. The canadians got different cowl plates and such but they still got smog heads in latel 68-70

FWIW there are actually TWO TYPES of non smog heads. On car #48 the casting was designed with no thought to future smog ports. But on car #132 you can see that they are flat spots purposefully designed into the casting for future drilling of the smog ports.

I have a U20 head with the threaded portion for smog cut, but the hole to enter the exhaust port is not drilled.

Wish I was that lucky. I had to put plugs it the holes and put up with the tick-tick-tick the whistle makes.

I thought there was a plug designed to address that issue?

All you need is a plug that fully seats to the bottom of the tapped emission hole (I have them naturally). There is no need to fill the tiny (1/4") space at the bottom unless you really want to.

What WILL whistle notably is if you just use a hardware sourced pipe plug. Those only go in a few threads and leave a large open cavity. Chirp chirp chip.
