Yes, glidein, it's often the most expedient way, particularly if you're fitting a more radical cam or have skimmed the heads and want to use adjustable pushrods. You'll save time and hassle so it's also a pay off if you're putting your bike into a shop to do it ... lift the top end costs.
It depends what you want to achieve. If you don't want to inspect and redo or develop the head, then it's probably the way to go.

Generally a 10psi difference between the two is acceptable... you have a 15psi difference there. Might be getting into a bigger job than you planned on.

Not acceptable for me, but that's me, good for some as long as it runs.

border line...
You are border line to doing a valve job that is what I would think based on todays fuels and your mileage. The rings are probably still good but with the addition of a new cam I would do the heads. Redo a compression test with oil and then a leak down to confirm..

stock compression on your bike should be around 150psi +/- 10 the 130 is to low. and the difference between cylinders should never be more than 10psi.
now you need to locate the problem by doing a leakdown test to find out where your loosing you compression if you don't have a leakdown tester
you can put one ounce of oil in the cylinder and do the compression test again if the compression comes back its your rings if it doesn't its your valves

Reread Schex3x's post #45. It's not the amount, per se, it's the difference of the amounts. I have no stake in this but perhaps you could PM Scott@hillside and get his estimates for a nice overhaul. No need, can the wants, to buy a Wood w8H and all other 11:1 pistons and the accompanying financial mess. Hillside is a proven site sponsor. Heck, pm John Z and ask for his recommendations and pricing.
