8% is way too much. If you want a reference, Gangplank's orange heals for a little less than double that on a much longer cooldown and higher mana cost.
Personally, I'd just put some sort of HP scaling on it. Like, +1 flat for every 10 bonus health. So +10 healing for every 100 health he builds.
Why not, that sounds pretty good. But that would be a bit OP as his healing doubles below 50% his own HP. It should be 1 per 25 Bonus HP.
Yorick in S8 is gonna get a shit load of HP, so this is gonna make his Healing insanely powerful, I tried this build and I got

. at Iv 18, at total He had 4485 HP with it without any proc's from Grasp. right now, His Q only heals for 106.6 and 213.2 (with
) But if it heals for 1 per 25 bonus HP. He is gonna heal for 221.156 to 442.312 with SPV
Right now as of this date, Resolve grants 180 HP in the PBE, that's 7.2 extra HP above 50% Hp he gets from Q hits.
So I'd say that 4 per 100 HP would be reasonable since he builds spirit visage. which he will nine out of ten times and the healing wouldn't really be that OP.
