timing chain won't fit

WHAT A DAY! #$%@
[fun in 93F driveway & 93 humidity]
ARP studs in.
Head on [by myself] #$%@
torqed dn to 60FP
learned springs have a up/down.
check and find 4 are upside down. #$%@
remove rockers and collets.#$%@
valve slides into head. #$%@
remove head.#$%@
R&R 4 of the springs.
install colletts & rockers. #$%@
torqed dn.#$%@
put the chain back on the sprocket and needed 1/8"
more lift to put the sprocket on the shaft. I removed the wedge
[with some difficulty] and lowered the chain slightly, perhaps 1/8",
and heard a plastic click. "oh no!" #$%@
remove sproket
shine a lite down there
blk plastic tensioner is poped to the left side,
push tensioner back in.with screwdriver
wrestle sproket back on. #$%@
1/8" lower than cam
While messing with it the tensioner pops 3 more times #$%@ #$%@ #$%@
I put it back but the chain has slipped on the crank. I hear/feel it slip and the #1 hole will not line up with the cam peg. [I had the sprocket and chain marked. The cam is TDC #1.]
so I rotate the sprocket on the chain so peg matches #1 hole.
The sprocket is still 1/8" lower #$%@
I put a screwdriver thru a sprocket hole and put a wooden wedge under it. By driving the wedge with a hammer I can lift the sproket upwards. I am concerned about breakage.

Is it low because the tensioner still out of place?

Is it ok to continue wedging the sprocket & stretching the chain?

I dont think it would be a good idea to wedge it. you should probably take the front cover off, that way you know everything is ok. better now then after you try to start and everything starts grinding and shrieking at you.

Had similar problem, even taking the precaution of using wooden wedge to keep from losing chain. In my case, the tenshioner came partially out, and could not get it right without having to take front cover off. If you do decide to take cover off, be sure when you go to reassemble, make sure you remember to put gasket goop in corner where block, and head meets front cover, otherwise you may end up with a oil leak after assembly. Take your time, Zliver
