Not unless you've got the eyes of a hawk or similar tbh it's hard enough to tell with no cases involved. Of you're planning to buy a 183 or something like that check for the spacer instead
there was like alot of gaskets instead of spacer so i took them out and it hits a head now so im guessing it is a 55 one as seller stated , does any one know what size spacer do i need for that crank ? im running malossi kit on that if it helps
Use the search? Been covered a lot of times. If it's been bodged so much it doesn't have the right spacer I expect port correction hasn't been done.
