I've got my 318 dismantled and I'm going to have it dipped/ checked before we go further.
I would like to decode the numbers on the block and the heads I have.
On the block:
1 side: 2.14.77
other side: 4006730-318-10
On the heads:
1221 and 2658920-5
I would appreciate any light anybody might be able to shed on this.
As always, thanks!
