book time on a timing belt assuming there are no siezed bolts is about 2 hours, to swap the cams is another 1.5hours or so.
I'd bank on a 4-5hour install just to be safe.
tuning said gears would be extra and dyno tuning is the only effective way in both time and cost to tune siad gears.
As for good brands...
a better question is what do you want as each brand has a different effect for a "stage2". BTW, asking for a stage2,3,10 is a bad way of looking for parts. ask what would best suit your goals, you will get better results/input in most cases.
i would stay away from any cam gear that does NOT have 5 gear bolts. there are some decent/cheap 4 bolt gears which will work, but i still suggest paying the extra $10-40 for a good 5 bolt gear. Less chance of gear slippage due to lessened clamp load of 3/4 bolt gears compared to 5bolt gears.
if you are doing all this, upgrade to a set of ARP cam gear bolts. while the stock bolts can be reused and will function fine, the T55 drive can easily be stripped on removal or install of the bolts onto the new cams and gears. plus the ARPs are a standard 12pt configuration so a standard 12pt box-end wrench can be used...
as for good brands, if you are looking at used parts, look strictly at FC, Esslinger and FR gears. they all share the same 5bolt design and all have hardend teeth.
STAY AWAY from the older Kents as the teeth are not hardend and can become rounded and cause the timing belt to ride back and forth on the gear rather than staying centered.
The new version "light weight" kenst are a nice gear but they only have 6ð of adjustment each way. more than enough if your cams were PERFECTLY degree'd in but if you are out 2-5ð, which is common, you have effectly eliminated much or most of your adjustment.
the FR, FC and Esslingers all have 10-12ð each way of adjustment which is another reason why i suggest them.
as for cams...
they are all good cams.
i really like the Crane2s for a good all around cam.
the FR2s have a little less in the middle and a little more up top than the crane2s.
the Crower2 are more of a high midrange/top end cam.
the Kents are also a good allround cam but for the price i suggest the Crane2s for a better drive, the kents will make a bit more power peak IIRC.
I'm not super familiar with the CATs or the Comp cams but they are not much different from the ones listed above i specs so i would imagine you will see most of your gains in the top of the midrange to the high end.
with any cams, it's not a bad idea to look into a custom tune, even if it is a basic tune if nothing more than to bump the idle to 1000rpm for a smooth idle.
almost all of the cams above are designe to make power between 2200-6800rpms. some make a little more down lower while others make a little more up top, both sacraficing the opposite to achive the end result.
good luck in your search, if you have any questions, please ask away!
