I have just got a hold of a pair of zl1 heads that need repair I did not pay much for them they would have got thrown in the trash if I dident see them.. The dates are 9-25-69 and not the more common 70-73 service replacement heads. I need to know if it is worth restoring them and who can restore them. or is it a lost hope Thanks Josh i will try to send pic's but if i cant and you want to see heads. i will mail you some
