Title: ZL-1 heads
Post by: black69 on September 10, 2010, 03:52:55 AM

I just picked up 2 3946074 heads. Where are the dates? I looked at them today and it was not obvious in a quick glance.
Are these fairly rare to find, or did they offer a lot of over the counter heads?
Would be neat if they were truely 1969 heads.

The casting date is on the bottom side, on the end intake runner.
