I think You misunderstood the nature of the question, have You checked it before meant 'this engine/combo as is' before, i.e. were the marks where they belonged & now they're not. And I've worked on cars for over 4 1/2 decades, over 3 1/2 professionally, and I've accidently hooked the wrong one avoiding hot mannys/headers.
I can assure You Del means no disrespect either when asking these questions, He has gone out of His way & has helped a TON of Members here.
Hope to see pics of Your rectified timing marks...peace!!
