Cant get car started after replacing lower intake manifold gasket.

Car drove in. Clients complaint was that it was smoking. Noticed that there was no coolant in radiator. Filled with 2 gallons but had to keep pouring small amounts in until I had put a total of 3 gallons in. It was not coming out the tail pipe so I checked the dip stick. Found about an extra gallon of water in the oil pan. Tested compression. I have about 90 psi on all cylinders on first crank when cold. Builds way 90 psi on multiple cranks. I cant figure out why it wont start any more. I believe the timing is off because I had to take the distributor out. Could see small coolant leak in front of intake manifold so I replaced upper and lower intake manifold gaskets. I have viewed multiple youtube videos but my distributor does not have the timing marks on it that correspond to the ones in the videos. Also I do not own a timing light or OBD 1 that plug in. I should be able to get timing close enough for the car to start but I cant find the marks on top of the distributor. I have found one on the side but I'm not sure about the final position of the distributor because as it goes down it rotates. I have an all datadiy on this car and I cant seem to find the info there either.

Review
1) Car drove in fine.
2) Car started and ran while I was adding coolant to it.
3) Could not get car to start after I removed distributor.
4) Distributor marks are not the same as they show on youtube.
5) Distributor rotates as it slides in.
6) Not sure of final correct position of distributor.
7) Distributor seems to be more electronic than ones shown on youtube.
