I'm currently building a 6.5 creedmoor on a Ar 10 platform. I have a 20" barrel from black hole weaponry. Would I be ok running a rifle length gas tube and adjustable block or not? thanks, any help is appreciated. I've ordered almost all parts from juggernaut tactical so far.

Would think a 20” barrel would be rifle length gas, but you should confirm to be certain. And would suggest an adjustable gas block to allow dialing in gas/ejection/bolt lock back with whatever you choose to shoot in it. Superlative and SLR make quality GB’s for this purpose. If you go SLR set screw mount and the underside of your barrel doesn’t have a flat, would suggest their jig for dimpling the barrel for set screws. Or, go clamp on. Regardless, make sure your hand guard has clearance for whatever GB you run. Lots of info here on builds with the hit of search function.
+1 for SLR adjustable gas blocks. The set screw or the clamp-on will serve you fine. Yes, a rifle gas will work fine on a 20" barrel.
