Default Secondary chain tensioner replacement

I am planning on replacing my secondary timing chain tensioners. I have both cam covers off and waiting for parts. My question is I have my Jaguar tool locking in place on the A bank with the flats level. However on the B side the cam flats are a little off with the A side locked down. The cam flats are close, but not perfect. Is that normal? . It seems that all four flats should line up.. My plan is to do the A side first with the Jaguar tool in place, then move the cams on the B side and place The Jaguar tool on the B cams.
Thanks for your time.

I believe that slack in the chain combined with valve spring pressure will turn the cams slightly. I did the job with 2 tools so that wasn't a problem, but I remember one bank going a little out of alignment when I removed the tool. Someone on a forum said that was normal and okay, as long as the cam bolts were tightened with the cam locked. Maybe a tech will weigh in. Did you use the tool to lock the flywheel?

Hi Mike, no I do not have the flywheel locking tool in place. I never thought to do that. I did not think it was necessary. I will put it in If I need to. Not sure

The locking tool ensures that the cam timing is in line with the correct settings- otherwise you are just guessing and hoping it's right.

Yeah, use the locking pin.

Also use the chain tensioning tool to insure that all the slack is taken up.

When the party is over, with the crank alignment pin still in place and the locking bar removed, the right side flats will be tilted slightly to the center because of cam spring pressure. The left side will be almost perfectly aligned.
