Here are the bolts I had left over. As far as the ones I used, I tried to use the ones that were as close as possible to the sizes the manual/Mr Tidy's instructions specified for each location. Then like I said, I didn't put any in the "spacer" because the manual didn't show anything other than a picture and didn't specify bolts/sizes going there.

I'll take a look that repair in the manual and see if I can tell where they go.

I really do appreciate the help. To save some time, here's the page I was talking about that show installing the spacer. It seems to indicate bolts go there but then doesn't say anything about them other than torque specs. I'd just have to guess at what goes where unless you guys have any ideas.

I have to take the top end back apart anyway to check the valves, so it's no big deal to put these in. I still don't understand why it won't hardly turn over though unless the valve clearances are way off and I don't think they are based on what I checked yesterday. It sort of seems like the compression is too high for the motor to turn over.

Yeah the spacer has 4 or so bolts that go in it before the cover goes on, the number I'm not exactly sure, but they're quite a bit shorter than the ones the cover uses to pass thru the spacer. Line out all your bolts in groups before reinstalling everything and do a "dry run" without tightening anything just to make sure you're using all the bolts correctly.

The fact that compression seems high makes me wonder if the decompression assist is occurring. Did you disconnect and remember to reconnect your decompression solenoid? The positive thing about seeing good compression is that your cam timing is probably correct. Make sure that decompression system is activating and assembled correctly.

Maybe some others can chime in with some ideas here too.

Re:Firing on one cylinder 3 Months ago  
The page you posted lists the number and length of the bolts that go in the valve covers. Find those and separate them out and what's left over should be used for the spacer. Surely you kept the bolts for the cams and cover separate.

Now, you said it's difficult to crank. I'm thinking that the pushrods are in the wrong lifters or #1 cylinder (rear) wasn't at TDC when the cams were installed or the cams weren't lined up properly. The rocker arm adjustment shouldn't have changed. Be careful and not lose any of the dowel pins.

There is a tech bulletin issued in '01 that corrects the pushrod positions. I'm looking at it now and it shows the intake pushrod on the front #2 cylinder on the inside lifter and on the rear #1 cylinder on the outside lifter. Another good reason to make notes when disassembling things.

Re:Firing on one cylinder 3 Months ago  
I just noticed something - In the drawing of the engine at the beginning of section 5 it shows both intake pushrods in the outer lifters. Maybe someone here who has their valve covers off can chime in.

In the drawing on page 5-14 it shows the 12 bolts for the spacer as 25 mm (0.98 inches) long.

I wonder if the shouldered bolts in your picture were designed for the rocker arm shafts.

Re:Firing on one cylinder 3 Months ago  
Agree it could be 180 out because it will still have compression. That would explain the no start and the trying to reverse the wire locations to get it to fire.

I also think those could be the bolts for rockers because the four in the middle in the picture have the long shank, like the rocker bolts should have.

Did you remember to install the decompression rods??

All that is necessary when installing the cams is that the rear #1 piston be at top dead center. Doesn't matter if that was the exhaust or compression stroke when the cams were removed as long as they are lined up properly the cams will determine which stroke the engine is on.

+1 cams determine as long as rear cyl is on top. 180 crank rotation from there would put the front cyl up and he don't want that.

Re:Firing on one cylinder 3 Months ago  
Actually if you lined up the dots on the cam gears before you removed it then lined up the dots when you installed the new cams none of the other shit matters. That is as long as you didn't turn over the engine with the cams out. Did you reinstall the decompression rod and all the rest of the decomp system correctly and without bending anything in he linkage? If you think something is wrong with the cam installation remove the cover and roll the engine around to see if you can get the cam marks to line up. if you can the cam installation is correct if you can't get them to line up then you found the issue. If they line up the issue is in the pushrods location or decomp system.
