Hi Dan,
guts effort mate! I'm doing two Gen II heads at the moment, fitted new guides to one head, now putting them back together. It's not a simple job.
You can use zip ties to keep the chain on the cams, but the cams are still going to be in the way if your swapping out valve springs.
What sort of valve spring compressor? You need to make really sure it doesn't damage the walls of the bucket bore, i.e. the walls the overbucket slides up and down against. I use a thin tube of nylon to protect the bore. I use seal picks and a magnet to get the keepers out and the seal pick again to get the valve stem seal out. (Again be very careful not to damage the bucket bore.)
Two engines to reassemble pronto plus a house full of screaming billy-lids and a job that takes up more and more of my time? I'd love to help but....
There's easier ways! Ahem, why are you changing the valve springs?

My new springs, retainers, keepers and seals have arrived and im now getting ready start in the next few weeks. i have some questions i hope i can have answered.
1)I plan on doing this with the motor still in the bike, does this pose any problems?
