Valve stem oil seal replacement (head-on)

[alundra]

Hi, guys.
I tried to do this, this afternoon and i'm in trouble now.
I used this:

I can't compress enough to remove the keepers.
I also notice that when i compressed it, the spring isn't loose enough, it compress upwards, i mean that the spring retainer don't go down like the retainer and keepers stuck.
And i also notice even i'm at TDC the valve can move like 0,5 cm down the piston.
Must i use some rope?
Thanks in advance because i need to fix my car for tuesday.
Cheers.

I used a air valve holder and a sealy spring compressor when i did my corvette oil seals. The air hold tool makes the job very easy
