Number 20 stamped in cylinder head
Im reposting this question here to try and get more viewers. Plus, the 81 pickup I have has a laser block. So..
My old 81 pickup has what appears to be a laser block, but I havent removed the intake or exhaust to identify the head for sure. I did notice the number 20 stamped inside the mechanical fuel pump passage/boss in the flange. Does this mean anything, 20R (thatd be cool), nothing? Thanks for any help. I figure someone out there knows what the number is for, if anything.
Knowing what head I have will make ordering parts in the future easier and save tremendous time. Thanks
