** i apoligize in advanced if it is in the wrong forum

well i recently purchased a low mileage jdm b18b. motor was extremely clean. block, pistons, belts etc.
when i took off the head though i noticed some slight scarring/gashes in the inner walls of the head.
im not exactly sure what couldve caused this, or if its normal at all?
let me know what you guys think. thanks
here are some pics:

dayum.. looks like the first owner tried cleanin it up.. did u find any metal shaving in the head or i meant small pieces of metal in the head?

ramrod

none. zero. clean as could be. like i said it was in great condition.

but lets take the situation, and say that he did clean it up. what couldve caused something like that? could it have been anything to do with the valvetrain components? rocker arms? it doesnt seem like it to me.

more importantly, will this have an effect on anything?

SockEG

it's possible that happened during assembly of the head and compressing the springs. if there is not any shavings or other signs of damage I wouldn't worry too much about it.

ill make sure and clean it up really good before proceeding with the build.
thanks for the input

Every head I've seen has those marks to some extent or another. I firmly believe they are a result of the manufacturing process.

Yea I have a B16 and an ITR head and i have similar marks in both.

I also have these marks in my ITR head as well. When I first saw them I was a little worried but looking at pics of everyone else's head's these marks appear to be pretty common. Just like others have said this looks like a manufacturing mark to me as I have seen this on quite a few heads now. Good question though and good pics illustrating what you were asking.

thats because someone tried jacking the valve springs with a pry bar..

j/k...they are normal

seems like scrapes that could have been caused by a valve spring commpressing tool...while changing valve stem seals and whatnot.

lol

thanks for the responses everyone. i guess some heads do and some dont then, my previous b16 had no such markings. it probably is due to the manufacturing.

thanks again

thats just from the person at the factory removing casting flash, no big deal, your motor is fine

Maybe the guy that owned it before you thought that that was the way to " port and polish " the head LOL!!!
