me being over zealous with assembly lube, and it was in intake rocker, and no they were the original rockers..... 
I thought that might be the problem, but was dreading breaking her down that far again.....

It is (kinda) strange IMO - no offence - that the oil pressure wasn't strong enough to push the pins into "vtec position".
@ 6000 rpm there would be around 8 - 8.5 bar (120-125 psi.) of oil pressure.
After all the narrow passages you may end up with (?) 5.5 - 6.5 bar (80-100 psi) at the pins?
Pin diameter is (?) 7 - 8 mm?
That gives a minumum force of ... 20 Newton pushing the pin away.
Okay, minus the spring pushing back.
Lets say 17 newton = approx 3.8 lbf.
And all the parts are hot too.
Hmm...
Maybe you used glue instead of assembly lube?

No worries, they are lubed now.
I had applied an excessive amount of molly lube on the vtec pins, which according to the manual should just be oiled but I was feeling crazy and threw some lube on them anyhow. Well that's why the manual says use oil, the thick, glue like lube galled and froze my pins,

when i reinstalled my cylinder head... i didn't lube it up.
damnit!
i didn't read anywhere in the service manual that spoke of lubing that shit up.

no offense taken, it seemed more like a vacuum holding it oddly enough. it took a rather strong magnet to get it free, possibly some debris lodged in it as well. Don't know really, but once I got it free and re assembled, she ran like a scalded cat.
