Yes and no. Yes it's okay, above min weight. No being they will likely be a problem hunting if you use fixed blade bheads due to their low FOC. Back when Excal used GT's much the same as your Firebolts, they advertised a 3" group at 25 yds and got it.
I have so many GT's, they are all I shoot, but the Excal forum guys are having great luck w/ Firebolts and the 150 gr 'Boltcutter' bheads.
I think some of the packages come w/ them and 150 gr points now.
I found min weight arrows and FFF's to be a nasty combo w/ my Emax, lots of noise and vibratation. Don't know how much of that your 'V' bar will take out for you.
You can get around the bhead/FOC thing by shooting 100 gr mechanicals.
