change 6L6GCfor6L6WGC in 68twin reverb??

[x66]

I'm fairly new to this. found some NOS RCA 6L6WGC from a military base down here and I was wondering if it OK to put them in my 68 twin reverb.
the tube chart on the amp say 6L6GC.
Some sites say you can swap 6L6GC for 6L6WGC no problem some other say it wont work and no explanations
Can someone give me a little help?Thanks
